I'm using a ATI TV Wonder VE I just got because I read it worked well.
You think the VIDIOCSYNC problem is occuring because of my tuner card?
One thing I've noticed is if I don't have my mixer settings set right
(setting capture and line in volume in alsamixer) and I turn them up
while 'mythtv' is running, this VIDIOSYNC message starts appearing
immediately afterwards. But if I have all the mixer settings right
before starting 'mythtv', it works for a while, I am able to change
channels, but without fail the mentioned lines start exploding onto the
console after about 15-20 seconds.
