It's not that bad, I can do 320x240 at 20fps grabbing & saving to a file
while doing simple masking operations IN PERL, on a much slower machine
(and realtime compression of 720x576 at 25fps as well ;)

If your processing pipeline looks like "grabbing -> transformation ->
display" then you should look at some tv viewers (like xawtv) or one of
the many paytv-decoders, which are designed for realtime performance.
