Perhaps the firewire driver for XP is the root evil here. The faster
machine should not be the cause of a bottleneck. XP is where they
decide, in their infinite wisdom, to remover the DOS VDM from the system,
and IIRC I/O drivers may have taken a hit when they went through
stripping things. Is your XP all loaded up with the patches, and service
packs, etc.?
The other thing would be the capture software, of course. You could
boot up knoppix and see if you can perform a better capture session from
within that.
DL and burn a knoppix 5.1.1 CD or DVD (the DVD is a better bet for vid
cap stuff being loaded) Boot the disc, and see what Linux had to offer
about a year ago. It likely has the best picks of whatever everyone used
back then.
If that works, I'd blame either the drivers in windows (blame windows)
or the software is having a problem with the stream compiled by the
device and the two are not compatible (unless it has settings). The is a
lot of windows based free cap software out there, but many are nagware or
crippleware. Anyway, there are a few ways to tell if it is the box, the
driver or the new software package.
