[mythtv-users] PVR-350 TV Output

There was a sh!tlist of faulty VIA chipsets floating around the mailing list.
Basically any kt-x33 chipset has DMA issues which *may* be the cause of the
described behavior. I'd take a wild guess you fall in the same statistics.
I could very well be wrong. Wait for second opinion.
Another suggestion, change the line (in /etc/modules.conf) that reads:
options ivtv ivtv_debug=2
options ivtv ivtv_debug=7
run depmod -a `uname -r`
then do tail -f /var/log/messages before you start myth* and watch for
Myth itself *cannot* lock up a system since it's a user-level application. A
kernel-level module (ivtv, ivtv-fb) can lock up a system due to a deffective,
buggy piece of hardware. Get on the ivtv-users mailing list and ask for help
there. Every other day a new thread is started about DMA problems. Go to
ivtv.sf.net -- the ivtv home page.
And finally, don't give up yet -- there's hope. Once you get myth working,
it's a treat. So sweet.
