My guess would be that it's the ATI driver for Xfree4.3.  I'm using SuSE
8.2 as well.  I don't have a DVD drive in my computer so I cannot speak
regarding DVD playback performance issues.  I am however, having similar
performance issues with every other video type I attempt to play.  I've
noticed that it isn't just a problem w/xine's xv playback, but this
issue also appears when using MPlayer.  I cannot watch .mov files
anymore, as the performance in the radeon driver for X4.3 is so poor
that the video lags behind the audio almost a full 5-10 seconds
w/dropped frames.  I did NOT have this problem running the same files
through the same versions of both xine and MPlayer under SuSE 8.1 and
xfree4.2.  This might be an issue that needs reporting to the XFree
people.  I know the new ATI drivers support some of the newer radeon
cards, and therefore are probably buggier than they used to be due to
new code.  Just my $.02
