I have a bunch of old VHS tapes that I want to move to DVD, but I want to edit them on my computer. (Take out commercials and other junk) I guess I want to buy one of those VHS-to-DVD machines to make "raw" disks that I could then load into the computer for editing down to the final versions. The video card on my computer doesn't have external inputs. Anybody got any recommendations on how to proceed, what hardware to get, and what software to use?
