You could do it but it would be kinda tough. You'd just have to rip each DVD, convert to .mov and open it up in an editing program, cut the shit out you don't want, export to an .mov and then burn to a dvd. I personally wouldnt waste my time.
dont waste time on this because short of finding and downloading the clips, you would have, like said above, download handbrake lite, rip them onto your comp which could take hours, and then edit, and then burn
