Could you (or anyone else who has managed to get it working well)
share the settings that you use: inc extra audio buffer, aggressive
sound card buffering and esp the RingBuffer size compared with RAM on
the machine?  I'm still finding it hard to get completely smooth
playback on my system (XP 1900, GeForce MX 440, FC4/2.6.14, NV 7676).

My Playback settings are:
 
Deinterlace Playback ENABLED, set to "Bob (2x framerate)"
Preferred MPEG2 Decoder: Standard XvMC
OpenGL Vertical Sync for timing DISABLED (this caused problems for me when enabled with a previous SVN release.  I have not tried it with this release)
Realtime Priority threads ENABLED
Use video as timebase ENABLED
Extra audio buffering ENABLED

Thanks,
