Marcel,  I have (had) the same choppy video problems as you.  (and I think many people do)  For Xine I have tried the -xshm option, and while it did smooth things out, it also caused tearing for me on moving objects.  I then tried -xxmc instead.  This has been the best option I've found so far - video is quite smooth (though I haven't compared it back-to-back yet with my standalone DVD player). 

As far as MythTV goes,  Bob deinterlacing is the only way I can get good smooth video.  XVMC will as well, but it's fairly unstable for me.  The only drawback to Bob is that it causes the OSD to flicker a bit.  I can live with that, however, though I hope someday it might get fixed.  :)

Hi Marcel,
I think I remember someone posting on this and the fix was the
-V xshm option. Like so:

xine -pfhq -V xshm --no-logo --no-splash %s

Good Luck
Dennis
