I failed to mention in my initial post... all of this is possible on windoze as well. I just don't have the time or resources to do the tutorial. If you have a Windows XP computer with a firewire (IEEE 1394 or iLink) port, you should be able to do this too. MPEG Streamclip and Quicktime are crossplatform, and I know that Roxio makes DVD burning utilities. You will have to find some kind of Firewire capture application and DVD authoring app (to replace the AVCap and DVD Studio Pro steps). But the process should be the same: Capture via Firewire, Convert, Build DVD, Burn DVD.
These guys have a similar tutorial for using windows:
I also have seen this before:
