[mythtv-users] Occasional jerkiness during DVD playback

[Jon Boehm]

I switched to xine for my dvd playback for this very reason.  I found that
the occasional jerkiness always happened around a chapter change.

I have a script called dvdplayer-launcher.sh which I call instead of
Internal.  Look thru the setup menues on you mythfrontend you will find
where the dvd player is selected.

It looks like this.  Note: I have a tv and a projector, that is what the if
and grep stuff are about.  I also have not desided if I like the
deinterlacing that is why there are commented out lines.

#!/bin/sh
f=$(/bin/ps axu | /bin/grep mythfrontend | /bin/grep :0.0)
if [ "$f" ]; then
    DISPLAY=:0.0
#    /usr/bin/xine -pfhq -D --no-splash dvd:/
    /usr/bin/xine -pfhq --no-splash dvd:/
else
    DISPLAY=:0.1
#    /usr/bin/xine -pfhq -D --no-splash dvd:/
    /usr/bin/xine -pfhq --no-splash dvd:/
fi

Good luck,
Jon

I have an EPIA SP based Myth box.  I have XvMC working and video
playback is usually very smooth and using only about 20% CPU.
But when playing DVDs, once in a while, usually on scene changes
where the whole field is different, I get a few seconds of jerky
video and stuttering sound.

What could be causing this?
