Another symptom, after I change the channel I loose audio and I see buffer underrun errors. I'm at work and can't post the log file. I think the problem is in the channel changing though. Fedora 11, Myth 0. Is there a better or different way to change channels? Thanks in advance. Re: change channel script and irsend errors on FC11 [ In reply to ].
I simply used the one in the contrib area of MythTV. I had to change the gap timeout slightly longer, but otherwise worked as-is. Channels do not change from myth. No blinky light on my blaster. T That card cannot recognize digital or HD broadcasts. The author of this paragraph has measured recording three 4. MythTV can integrate with a separate set of scripts maintained by the XmlTv project to provide guide data for countries outside the USA. Please refer to the XmlTv page for more information.
You need one capture card for each program you wish to record at any given time, and one extra, if you want to simultaneously watch live TV. The short answer is as much as you can afford. If, however, you're not made of money, here are a few guidelines:. This functionality has been moved to the Playback Groups setup menu. Here you can create Groups to apply different skip, jump and stretch to any programs you want.
Supporting multiple database engines is not considered a worthwhile use of the developers' time. Cleanup: This article or section may require cleanup. Discuss the issue on the talk page. There are many informative posts on this subject in the mythtv-users mailing list archive by Cory Papenfuss. The 2. The main piece of advice is to ensure that the graphic card you are thinking of has Linux drivers that support the TV out functionality until recently some ATi cards had problems with this.
If noise is important to you then try and get one without a fan. This has the advantage of working with any graphics card that has drivers available, and is relatively simple, but the output probably won't be frame- or scanline-accurate. If you're a dab hand with a soldering iron and you live in Europe then you can cheaply make a circuit which will enable you to take the VGA output of the video card and plug it straight into the SCART socket on your TV.
Instructions on how to make the circuit are here. The author of this paragraph recommends using Linear Blend deinterlacing, rtprio scheduling by editing limits. Recommended PAL modelines are:. This is a particularly a problem, for example, if your TV is widescreen, but only accepts x There is the possibility of limitations with supported resolutions for this case as well.
Therefore, if your fonts do not look right, you first need to ensure you have installed the font your selected theme is using.
If you have the font installed, and you still don't like the font sizes, you should choose a different theme. Fonts distributed with themes are loaded automatically. Note, however, that some of the MythTV themes use MS core web fonts often the msttcorefonts package in many distros , which may not be redistributed.
However, many other applications are designed to operate in a limited range of display pitches dots per inch. To find out what your vertical and horizontal pitch is with the X display running use the command:.
If the response from this isn't x dots per inch, you may want to change your system configuration to force X to calculate dimensions appropriately for non-Myth program usage. Unfortunately, there are many ways to specify the pitch, but X will use only one. The "-dpi" command-line argument to the X server takes precedence over all others.
Note that some distributions use this argument in their X start scripts such as the "startx" script or by calling "startx -- -dpi 75". If your distribution does this, you'll need to modify the start script to either specify DPI or simply remove the option preferred and use the configuration files as described below.
If your system does not specify a command-line argument to set the DPI, you should configure the pitch using the X configuration file XF86Config or xorg. The standard X approach for configuring the pitch is through the "DisplaySize" setting. Under the "Monitor" section in your X configuration file. See the Display Size page for appropriate settings for common monitor and TV resolutions or if your display is using non-square pixels i.
It's important to choose a DisplaySize whose aspect ratio is the same as your physical display's aspect ratio, so if you have a TV, choose a DisplaySize. If you have a TV or monitor, choose a DisplaySize. If you have a widescreen monitor, choose a DisplaySize.
Note that you may also specify a font pitch of dpi which is not the same as specifying a screen pitch of dpi by adding the following line "Xft. If this doesn't solve the problem then the chances are it's a broken font package or something. Feel free to post the problem to the mailing list at this point, but make it clear you know you're running at dpi or you'll get lots of requests telling you to make the changes listed above. When you use MythTV you will find out that it is a very useful piece of software that can completely change the way you watch TV.
It is not, however, a means to circumvent copyright and this list is no place to be asking for tips on how you should do so. See, also, Mailing List etiquette. You probably have a filter set from a previous session.
Myth has two plugins called MythMusic and MythVideo which can be used to handle audio and video libraries, respectively. However, mythfrontend requires a running mythbackend to connect to, and mythbackend requires at least one properly configured capture card. If you're going to, for example, have your cable TV feed temporarily disconnected, and you don't want to record static, but you don't want to lose your schedules:.
A1: Go to the "Upcoming Recordings" page of the frontend or MythWeb and add a "do not record this episode" override for each scheduled recording during the expected service outage. This solution will not work for episodes with empty subtitles or descriptions because they are exempt from duplicate checking. You can simply delete these recordings after they have occurred and they will have no impact on future recordings.
A2: Use the frontend or MythWeb to edit each recording rule and set the "Inactive" flag. If you have a large number of recording rules, this is probably not a good approach. It also is difficult to undo after the fact if you have some recording rules that are normally inactive i. A3: Modify whatever starts your machine's backend to add the --nosched flag, like this:. This will cause the backend to run normally, but not execute scheduled recordings.
When your problem has been cleared up, remove or comment out that switch. The scheduler, by default, will not bump programs of higher priority even if there is a later showing as it assumes that you want to see higher priority shows sooner rather than later. To override the scheduler's decision, you may create override rules to tell MythTV to "Do not record this showing" of the earlier showing and, if necessary, "Record this specific showing" of the later showing.
If you feel it is acceptable to let the scheduler bump high-priority recordings to later showings automatically, there is a setting in the frontend setup to allow rescheduling of higher priority items that can be checked.
Just be aware, that exciting episode of 24 might be recorded a week or two later leaving you in the dark and plugging your ears as your friends talk about it.
By default MythTV will not record shows it recognizes as having already been recorded. In the "Upcoming Recordings" display, the encoder that is going to be used is shown. There is no corresponding field in the "Previously Recorded" display, because the encoder numberings could change over time. The way to find out which encoder was used is to consult the myth-backend logs.
First, make sure that the media monitoring is checked in the general settings. Also make sure that it is enabled in the plugins for MythVideo or MythMusic. Lastly, check if your mount point for your drive is set to use filesystems of "udf, iso" instead of "auto" which can correct problems with lowercase directory entries failing to be detected on DVDs. See Removing Commercials for details. The simple answer is, "Because commercial detection is detecting, not removing, commercials.
Ensure that you've got the correct audio output device. Ensure that all your MythTV machines have different hostnames. Myth works out whether or not to stream a recording live tv or otherwise by determining the frontend's hostname. If the frontend hostname is the same as the backend's hostname, it will try to play the file 'locally'. Having different hostnames for machines is useful and correct in many other scenarios too! Also, make sure your frontend and backend have the same timezone and have roughly the same idea of what time it is.
This must be enabled in your hardware recording profile, it won't allow it to auto-transcode unless it is specifically set.
When you watch TV, the ability to pause, rewind, and skip commercials is because it is actually recording everything you watch. We also have an lirc daemon attached to each driver. This would be a good point to do some testing. The following script will allow you to send IR remote commands from the keyboard to change the channel on each DTA:. This Perl script borrows the best design elements found in the channel change scripts from these two web pages:.
This modified version permits specifying which IR transmitter will emit the IR signal. You will have to install the package sleepenh to have delays between the output of IR signals.
You run the script by typing:. Type a command such as:. I find a lot of black electrical tape can cure this problem. If you get one to work, but not the other, then you probably have a cabling problem.
I had the wrong type of ribbon cable bringing my serial out to the back panel. If you get no channel changes on either DTA; first did you remember to reboot your computer after you made all of those script and file changes above?
If that is the case then it is nearly time to integrate this setup into the MythTV backend. But first you will have to update your subscription to schedulesdirect. It is our intent is to provide cable box support for multiple tuners, yet still have at least one other tuner still tuning old fashioned analog cable. Your schedulesdirect. I still see all of the channels listed, but everything over channel 22 shows just snow. This channel lineup is fine for our newly attached cable DTA boxes, but we need an abridged lineup for the remaining analog tuner s.
You will have to log into your schedulesdirect. It is necessary to have both lineups so that MythTV knows what channels are supported by each installed tuner.
NOTE: After I added the new lineup to my account it took some time for it to be available via myhtfilldatabase. If you continue to have problems, you can try to readd all of your channel lineups:.
This is where the EPG channel lineup is defined. You will have at least one existing lineup there already.
