I'm posting this to the ivtv list because the version of ivtv I use
has the biggest affect on the output. I'm actually trying to play things
through MythTV, using the PVR-350 MPEG decoder.
I'm having a really hard time getting a good quality picture out of xine
when playing DVDs (actually DVD .iso images) through my PVR-350. It
worked fine in the past, but I've changed many things and now I can't
find any combination of ivtv, ivtvdev, xine video drivers (xv, xshm,
etc.), etc. that produces a picture that is correctly sized, stable,
doesn't drop frames, and has a picture quality that rivals playing the
DVDs in a real DVD player.
I had it working great once before, so I know it's possible.
I'd like to hear from anybody that *does* have a good working
configuration so I can try to replicate it. My details are as follows:
NTSC 4:3 CRT TV
Athlon XP1700+ w/512MB RAM
Gentoo Linux w/kernel 2.6.10-gentoo-r6 or 2.6.12-gentoo-r4
xine 0.99.3-r1
xorg 6.8.2-r2
ivtv 0.2.0_rc3-r5, 0.3.5y, 0.3.6e-z
ivtvdev 0.10.2, 0.10.4
I run xine like this (using xshm as an example):
xine -pfhq -V xshm --no-splash dvd://path/to/the/iso
At best the picture is jumpy (dropped frames) and has black lines
scattered throughout the image. At worst the image is gone (blue screen)
or divided into 2-4 tiles that are offset and appear to have missing
scan lines.
Some of the problem may have to do with the specific USE flags I'm
using, so I'll list them here for the benefit of anybody else who is
running Gentoo:
USE="mmx directfb ffmpeg qt xine divx4linux v4l -gnome kde alsa dvd
dvdread X gtk gtk2 mysql mythtv apache2 usb lirc"
My xorg.conf file can be found at:

If there's any other information that would be helpful, please ask for
it and I'll happily supply it.
Thanks,
Daniel Segel
