Well I tried this out of interest....

The audio was transformed brilliantly, but had frequent loss of smooth movement on the video rendering. Once the smooth panning became jerky in each scene, it stayed that way until the next new scene, which inevitably went choppy as weel later on.

Have others tried to burn a produced movie in Dolby 2.0 audio to 5.1 surround (DTS) without losing video quality, or am I trying something that's doomed from the start? :
The meek shall inherit the earth, if that's ok with everyone else....
