I am making a demo DVD- not trying to illegally copy commercial DVDs or anything like that (!)- but need to get material from various (non copy-protected) DVDs so I can combine them in DVD Studio Pro... is there a simple way of doing this without losing quality? I only need the video from the discs (they have no menus). They are SD TV programs- running about 30 mins each if that makes a difference. Thanks in advance for any suggestions.
