Very jittery video - any solutions?

[David Mills]

OK, SLD now installed and configured, vlc shows that it is using it yet the 
picture is still jittery with lots of 

vout warning: late picture skipped (0x818fb50)

I'd say I'm getting about 1 in 4 frames.  Here's a longer output:

VideoLAN Client - version 0.2.91_2001-12-14 Ourumov - (C)1996-2001 VideoLAN

...
vout warning: late picture skipped (0x818fb50)

messages.

For comparison I also installed the Windows version under Win98 on the same 
box (dual boot) and it works great.  Excellent picture.

Any other ideas?

David.
