Re-reading your previous e-mails, I see that you are in fact describing
the same thing. I wasn't sure before, but your explanation fits what I
am seeing.
Do any of the other media players handle things any better than xine? I
want DVD menu navigation; is ogle the only other one that can do this?
I'm using MythTV, and I have a special command for .iso file types - I
wonder if I could create a script to set the yuv-mode, call xine, and
then reset it when xine quits. I'll try that soon.

I posted a very similar question a few days ago. Look for the subject
"xdriver smooth dvd playback", it explains why you see the halting
motion. The response was to change the card to sync on field with:
ivtvctl -set-yuv-mode=mode=1
The big thing I'm trying to figure out now is if I can modify xine to
make this call when it detects a progressive or an interlaced frame.
If you set to sync on field and then play interlaced material, there
is a 50/50 chance you'll sync on the wrong field and all motion will
look flickery.
Another way to fix this would be to leave it in sync on frame mode and
convert xine output to telecine, but I don't think xine currently has
this capability. My guess is that so many people are getting
progressive scan tvs that this sort of thing is becoming archaic.

When playing DVD images (.iso's) with xine using the xv driver, I
experience what I think is called 'judder'. It's not exactly dropped
frames, but scenes with motion in them appear to jump a little
bit, like
a frame is being paused and then let go. This happens maybe twice per
second, and it's only really noticable in scenes with smooth motion
across the screen.
If I use the xshm driver things are mostly smooth, with only ocasional
tearing in scenes with a lot of motion, but there's a little less
detail
in the image.
This is with ivtv 0.4.0-r2 (gentoo portage version) and the 0.10.6
ivtvdev X driver, on an NTSC interlaced TV.
Is there anything I can do to improve the quality with the ivtvdev X
driver? Is there some setting I have wrong? Any other info I could
provide to help figure this out? Does xine have any options to control
this kind of thing?
Thanks,
Daniel
