how did you seperate the captured stereo PCM into the seperate dolby channels? particularly for the center dialogue channel? was this done using vegas or something?
I ask because I think splicing and mixing the new 5.1DVD ac3 in relation to the original stuff might be too much work, but it doesn't mean I can't pinch elements of it. however if we can take the PCM, and turn it into at least a reasonable surround track AC3 with a seperate dialogue centre channel that would be a big improvement.
