Is DVD better than DSS?
Yes. DVD is mastered as CCIR601 4:2:2 digital component video and utilizes 100% MPEG-2 data reduction. DSS, on the other hand, is 4:1:1 digital component video and features scalable compression schemes that vary from MPEG-1 to MPEG-2. In fact, the digital component video signal of DVD has the capability to rival the best studio masters.
