well in all fairness trying to stream the same video file to various sources doesnt work to well in my experience either
look at it this way . How good is your pc? how many hard drives does it have and how dvd readers does it have.
say like most people you have 1 and its a modest pc its what 15 minutes to decrypt a dvd then what half an hour minimum to convert to whatever flavour of avi you wish. Thats 45 minutes per dvd. Say you have 50 thats 2250 minutes of ripping which is 37.5 hours
Plus on top of that the chance some will go out of sync and some will require subtiles for foreign speaking parts
upto you op
