OK. Then it's minnetoka next, BUT I have two more trials to go and I have some issues to resolve first 
. I'm in a situation where I want to backup a number of my music BD's. Aiseesoft does an exellent job on ripping these, and transcodes to ( takes care of) ac3 audio format (mp4 container). I've tried a number of approaches - mpeg2_ts, h264.ac3 etc. (http://forums.creativecow.net/thread/145/870940)
How should I define the audio track setup subsequently in PPro - define a single master 5.1 , define 6 separate A-channels , or define 6 separate + one 5.1 ? From a number of tutorials I've seen this should be quite an easy task, but I can't get it to work properly. And I've come to realize that En does exactly what it is told to - but so far stereo, strero and nothing but stereo outputs. And thats not En's fault as the sound file shows up as "dont transcode" - but my bad somewhere else ...
any more help here?
