[mythtv-users] recording blank, only with mythtv

[Henrik Bentel]

Hi

I have strange problem. If I cat out /dev/video0 to a file, I can play it 
using mplayer. If I just watch live TV using mythfrontend everything is 
just fine.
BUT, if I record with mythtv, even just a minute, mythtv records only 
blank/black. And if I go back and cat out /dev/video0 again into file it 
also now records blank/black.
I have a script that I run as part of rc.local which runs 5-6 test_ioctl 
commands (sets width, height, frequency, input, output, tuner, etc). If I 
run this script manually after recording goes blank,  everything is fine 
again. But as soon as I record something using mythtv, it seems something 
gets unset or set incorrectly and I record nothing but blank.

When a recording starts I see in message log messages indicating mythtv is 
resetting some settings. The messages are "setting NTSC width" and "setting 
NTSC height".
These are the same messages that show up if I run my script containing the 
test_ioctl commands manually.

I've had mythtv up and running just fine since 0.13. Due to crappy maxtor 
drive saying good night I recently had to reinstall(Only Seagate w/5 year 
warranty from now on).
Luckily I was able to backup the DB, all important config files from /etc 
and mythtv users home directory. So my software configuration is pretty 
much identical to before the reinstall. And my hardware(except the maxtor) 
is also identical.

any ideas?

thanks,
