Very jittery video - any solutions?

[David Mills]

Hi,

I've just installed 2.91 or VideoLan.  The picture is very jittery.  When 
using -v I get the following:

> /usr/local/bin/vlc -V xvideo -v

Is there anything I can do to improve things?  How can I verify that xvideo 
is working?  I have attempted to activate dma but get the following response:

# hdparm -d1 -c1 /dev/hdc
 
/dev/hdc:
 setting 32-bit I/O support flag to 1
 setting using_dma to 1 (on)
 HDIO_SET_DMA failed: Operation not permitted
 I/O support  =  1 (32-bit)
 using_dma    =  0 (off)

I'm running SuSE Linux 7.2 on a 600MHz Pentium with 256MB RAM, a 32MB NVidia 
TNT2 card and a SoundBlaster Live card.
