If you are burning it to watch it on a regular DVD player it will take a while to encode the DVD assets. If you are just burning the file to a DVD then it depends on the speed of your burner. I would expect at least an hour in the second scenario. You are looking at letting it run over night in the first scenario.
Hook up your computer to the TV? The 1.5 PB has S-Video out which is good for DVD's. Dunno about the RBG, you'll need the S-Video-RBG converter if your TV doesn't have S-Video.
