MythTV record ends on the hour or half hour

Submitted by newtonjd on September 20, 2009 - 12:09pm

I have been attempting to record old home movies with mythdora and have been having trouble with the record function. Whenever in live TV mode I press the "R" button to begin recording but it times out whenever the clock reaches an even hour or half hour mark. For instance if I push record at 7:12 it stops at 7:30 and If I push record at 7:43 it stops at 8:00.

I believe the problem is that there is no program data to go along with this program and some setting somewhere has this as the default behavior of the program. My question is how do I make it stop doing this so that I can press the "R" button and have it record and then stop it myself by re-pressing the "R" button (or another button). Thanks for the help.

I believe you are correct; mythtv will stop recording on half hour boundaries when there is no other scheduling information.

You might try setting a recording schedule for a longer period of time.

In past when I've copied video tapes using my VCR, I would do so without mythtv. From the command line I simply issued a commands like:

$ # set input to composite input
$ v4l2-ctl --device=/dev/video1 --set-input 2
$ # maximize resolution
$ v4l2-ctl --device=/dev/video1 --set-fmt-video width=720,height=480
$ cat /dev/video1 > /path/to/file.mpg

Of course I had the tape queued up to near the starting point, and hit play after issuing the cat command. Then use ctl-C to stop the recording at the end of the tape. Afterward I would use a tool like avidemux to trim out the beginning and ending portions that might have leading and trailing static from the resulting file. I would also use mplayer launched from a different xterm to monitor the file during copy like so:
mplayer -vo xv -monitoraspect 16:9 /path/to/file.mpg

A bit cumbersome, but it worked for me.

NB I have a Hauppauge PVR-500 card which produces mpeg output. Make sure to use the correct video device (/dev/video1 for me).
