I hear that you can copy TV programs and cut out the commercials before making a DVD if you have one of the combos with a harddrive. Can you also use such a machine to edit old home video tapes before recording to the DVD? I have a Mac G4 and at present have to go from the VCR into a sony DVMC DA2 to go (anolog to digital) into my Computer. I think I'm loosing quality and the quality isn't great in the first place (old 8mm film put on VHS tapes). i want to edit these, make chapters with titles and bun to DVD and get the best quality possible. Any suggestions out there?
