Ok, for me the does seem to have been cleared up by changing my arts setup so 
that it works (I think the autodetection was going a little bit screwy, 
forcing it to use ALSA works and doesn't give me the white noise effect, 
which was indeed occurring on everything using arts, not just piave.).

I have noticed something interesting - if the arts buffer size is set too 
large (not recommended for video editing anyway), piave starts to play the 
video more slowly, which in turn seems to cause the audio to stutter. Setting 
the buffer size too small also makes the sound stutter - although that is the 
obvious one, where presumably arts cannot feed the sound card fast enough.

For information, my kernel is currently the Mandrake "multimedia" kernel, 
which I thought would be interesting to try out. I am not convinced that it 
is any better than the normal Mandrake kernel; to me it actually feels slower 
than the normal kernel.

Cheers,
Jason
