Yeah, btdt. I was not happy with using the patched MPlayer + the
PVR-350 framebuffer for playing DVDs. I had terrible problems with
framedrops and video syncing up with the audio! The audio sync problem
is the worst, I found that I needed a unique delay value to pass to
mplayer for each DVD. This delay value seemed to have a tendancy to
drift and, at times, when you push the REWIND button, you would cause it
to lose audio sync. You could get the audio sync'ed again by pressing
REWIND + PAUSE + PAUSE a few times to flush the mplayer buffers, but...
What I am using now is a Mad Dog GeForce4 MX 440 8X video card that I
picked up at Office Max for $79. The DVD playback is really good, there
is still some issues with software codec jitter, but now really all that
objectionable. However, if you are a purist, get a DVD player. ;) The
TVOUT of the NVidia card is really reasonable, there is also some slight
jitter issues when viewing an action scene, but is not too bad.
I am currently considering building a software controllable video switch
so that I can switch between using the PVR-350 TVOUT for everything but
DVD playback. I plan toggle the video before calling mplayer to play a
DVD. For watching TV, and recorded TV, the PVR-350 video is far
superior to the AGP card.
Oh, btw: Tyan S2495, Athlon 2800+ XP, 1Gig DDR, Mandrake 9.2, 370Gig
logical volume, Plextor 708A.
