A couple of complex questions:
1. DVD to computer ... this is basically a DVD-ripping
question. You can find a ton of information about this at
VCDhelp.com -- this site is huge, so look for the
tutorial and how-to areas in the left-navigation menu.
2. VHS to computer ... there are several methods to do
this: VHS-DV Camcorder-Firewire-Computer, VHS-analogue
capture card. If you just want to capture video for
placing on a DVD, you might want to check out one of the
Ulead or Dazzle USB products. (however, the mpeg video
most of them create is hard to edit within Moviemaker)
