All very well and good but the pvr-350 doesn't (or didn't)
work with X over the tv out with 0.2.0rc3c and FC3
I'm running kernel 2.6.9-1.681_FC3 and 0.3.1z (patched for ivtv-fb on
2.6.9 kernels)
One (stupid) thing I did was expect the sound to come out of the
soundcard,
If you're using the tv out of the pvr-350 the sound comes out of that
too.
Have you tried cat /dev/video0 > test.mpg then playing it back (on
another machine
maybe that's known to playback with sound)?
Also make 10000% sure you are using the correct msp3400.ko, do the
following to check:
cd /lib/modules/2.6.9-1.681_FC3
find . -print | grep msp34
Check to see what is loaded by
lsmod | grep msp
Check to see what will be loaded by doing
modprobe -l | grep msp
The FIRST one in this list will be loaded.
FWIW the line I use in my crontab (and works) for mythfilldatabase in
the UK is
(skipping the actual time to run)
/usr/bin/tv_grab_uk_rt --config-file
/home/mythtv/.mythtv/Terrestrial.xmltv | /usr/bin/mythfilldatabase
--update --file 1 -1 -
I have had mythtv up and running fine but at the moment mythbackend
keeps
crashing (an issue I believe is due to the xfs journaling partition I
have
/video on) but more importantly the box has just started to keep
crashing[0][1][2]
and I need to sort that out before I start playing with mythtv again :-(

[0] Up for 20days+ now crashing up to twice a day, I'm not sure if it's
something I've
done or something's broken. :-(
[1] With no error messages anywhere :-(
[2] I'm trying stress testing it with various things to confirm the
hardware + O/S is stable but I suspect it's hardware :-(
