<p class=MsoNormal><span lang=EN-GB>UQ Vislab vic doesn't do any transcoding
from DV (or HDV) firewire devices to other codecs, so if the codebase was

<p class=MsoNormal><span lang=EN-GB><br>
Well, doing raw DV without transcoding would be fine (if it were on both
platforms), since we can spare the bandwidth - that's what we're already doing
via the ExtendedVideo services on Windows, but we'd like to be able to move on
to something more cross-platform.<br>

Interesting, I'll have to try that out. Would vic theoretically be able to

We've seen it here on a couple of different systems - a Dell w/ a dual-core +
hyperthreading 3.46Ghz CPU, and Suns with 2x dual-core 2.2Ghz Opterons - so I
doubt it's CPU-related. Can anyone else chime in if they've tried the firewire
capture on Windows?<br>
