If "-vo xv" has trouble, but "-vo x11" doesn't, I would suspect the 
components that come later than libavcodec. For instance, I have a very 
similar problem with any video wider than about 750 on my TNT2 Vanta. I 
have very few videos this large, so I didn't know about the problem for 
quite a while. I get the problem playing the high resolution Matrix 
trailer (1000 columns wide), which is SVQ3. I transcoded it to MPEG-4 
using lavc and the result has the exact same problem, though my machine 
can play it without dropping too many frames. Both play clearly with 
"-vo x11", but have the junk with Xine.

You  talk about "movies of high bitrates, fast movements", but how about 
the frame size?
