How do I get my videos uploaded to my computer???

I've yet to find any software that comes with a camera that's worth anything. The easiest way for you is to finalize the DVD, "rip" it to your PC and then encode it into a more editible format. I recommend DVD Decrypter or DVD Shrink. They will get your footage off the dvd and onto your PC. You can then use something like Videoera (PC) or Handbrake (Mac) to encode it to a more editable format. Depending on what editing software you use, you may be able to import mpeg2 and even VOB files directly. But understand that you're already starting with compressed footage, so the resolution quality will not be as good as if you had shot native with MiniDV tape and captured to your PC.
Good luck.
