Bob, what are you talking about? DVD can't sustain more than 9.8 Mbps all streams combined and that on a replicated discs. The guy would do himself a huge favour if he buys CinemaCraft Encoder MP plugin for Compressor for less than $1K (American). The presets are to kill for, and it's the same engine as Hollywood's beloved CinemaCraft boxes.
Don't start on Adobe Encore with me, it can't do 100 passes on video, unlike CinemaCraft, its a buggy toy, compared to Compressor/DVDSP
