Post subject:  Live TV kills mythbackend
I have just completed an upgrade installation of R5C7, and I have followed the last 4 steps in CompileIvtv in the wiki, but when I choose "Watch TV", I get a black screen.

My output on the terminal is this:
2006-08-25 13:54:17.662 TV: Attempting to change from None to WatchingLiveTV

The last messages are repeated over and over again until I Ctrl+C. (I have only let them go for about 10 seconds.)

Has anyone else had this problem? Does anyone know how I can fix this?

Everything else works fine- I can even watch old recordings.

Is it a good idea to install a new version of ivtv from source?
My cards (two Hauppauge PVR-150s) are being detected properly and I can cat /dev/video(0 or 1) > /mythtv/test.mpg and play it back with no troubles.

Thank you in advance!

My backend log shows this before the segfault:

2006-08-25 15:19:19.401 TVRec(2): Changing from None to WatchingLiveTV
2006-08-25 15:19:19.631 RecBase(/dev/video1) Error: SetIntOption(...mpeg2bitrate): Option not in profile.
2006-08-25 15:19:19.635 RecBase(/dev/video1) Error: SetIntOption(...mpeg2maxbitrate): Option not in profile.

Does this help at all?

Oh! :roll: It was because I had not set up any recording profiles.
