UQ Vislab vic doesn't do any transcoding from DV (or HDV) firewire devices 
to other codecs, so if the codebase was merged as it stands now, it wouldn't 
do what you are trying to do anyway.

Have you tried using DV4Linux so that your Camcorder can be seen as a V4L 
device? I haven't tried it myself.

As for the flashing verticle line artifacts on Windows, I don't seem them, 
but I was using a quad-core 2.6GHz Xeon.

Cheers,
Doug
