I am want to make my own "On-Demand" service for my home pcs and media centers. HDD space is not issue. I have a bundle of dvds that I have ripped to my HDD. Each rip is one VOB file and only contains the movie. I want to strip the VOB file off all unnecessary headers so that it works like an ordinary MPEG2 file and runs on all media players. Also I dont want to recode to lose any quality. Any suggestions on how I might go by this? Changing the extension didnt work too well.
