OK, first we're discussing which video codec to use , now we're burning "data" discs. If each Tape is different, then each tape has to be encoded separately. You're talking about how the discs have to be in the same format for all the recipients. So, what are they going to do encode the files themselves? First and foremost, you're trying to do the work of a video production house on an outdated laptop. Why would you take on this project in the first place? Will more memory help? To a degree. a very small degree. Memory doesn't create more CPU clock cycles, never has, never will. Clock cycles transcode video. Memory just handles the info as it's being written to the drive. The is an age old fantasy here at TS, "I want to install more memory so I can run 22 programs, play WOW, encode video, and burn DVDs while I surf the net"! The answer's always the same, "um, good luck with that"!
