  Currently 2.6.18.  That helped, but then I added another capture card
and 2 more cameras.

  All the box does is the video work, as for shared interrupts it is
unavoidable, there are 3 capture cards serving 4 cameras (probably soon
to be 6).

  How slow/far behind depends on how many cameras are being viewed at a
time.  Resolution currently at useful limit (320x240).  I think I will
just try the PII-350 and see.  The real solution will likely be to get
my spare AMD dual up as my server and put them in there, but that
involves $$ again (registered ecc DDR memory).
