Anything's nicer than the G200, IMHO!  Good in its day, which was
some years ago.

Looking at our Linux box doing video capture under Linux on a
single processor Athlon XP1600, it took about 8-10% per stream.
So half an XP1600 was enough for 4 streams, using Hauppage
cards.  Haven't used Winnov Videum under Linux, so can't give
you a figure for that.

I'm not a Linux-savvy person, but if Linux can handle multiple
processors intelligently, I would have thought a twin 3 GHz
machine with, say 2 Gb memory, and a decent display card would
be fine.  I don't see that the overall parameters need be much
different for Windows XP and Linux, although the detail may be
as a result of driver availability or performance.
