Thanks, Ripi.  I just installed alsa, and it seems to have cured
that particular problem.  

But now, vlc seems to be suffering from a/v sync problems on my box,
and after you play a vid for a minute or two, it starts dropping
frames left and right for some reason:

vout warning: late picture skipped (0x8174950)
vout warning: late picture skipped (0x8174950)
vout warning: late picture skipped (0x8174950)
vout warning: late picture skipped (0x8174900)
.....

Odd.  My old Athlon-750 never had difficulties, so I can only assume
something else is different.  The CPU meter stays below 1% the whole
time.  Is top and similar tools even accurate for vlc?  I mean, I
would have expected to take at least a few percent of the CPU (a
1.53 GHz Athlon XP) to handle a SVCD-quality MPEG2 stream.

Thanks,
Dan
