I had all sorts of video capture stuff on the PC, but got a cheap DVD recorder to connect up to the TC - it's so much easier!
if you have something you want in better quality, do it at the 1 hour per disk rate, overlap slightly and import the lot into the video editing software - then join together (at a suitable frame) and export the lot to DVD with 2 pass compression to fill the disc.
(DVD recorders do every frame as a P frame, so re-doing it on the PC will make it smaller without necessarily losing quality)
