Ok,
(not snipping for full context)
It might be indeed a VM problem. I have noticed that Xine claims an
awful lot of memory (after quitting, some 75% of my 256M is freed up)
and playing a DVD also seems to claim a lot of swap.
Another thing might be the DeCSS plugin used. I've seen some skipping in
normal playback too using the d4d plugin. I just switched to the dmd
plugin from the VideoLAN site, and that appears to play a lot better
(currently watching 'Das Boot' which used to skip with the d4d plugin,
now it plays a lot better).
Anyone see comparable behaviour under recent kernels? I'm now running
2.4.16, and everything appears normal, except the dvdnav plugin still
causes skipping.
