I started to watch this tonight and found a pretty serious technical flaw that I can find no-one having mentioned in the thread.
I know there was some discussion about the troubles with upmixing stereo deleted scenes to 5.1 (btw, if you use Womble, it does that just fine automatically if you set the output to 5.1.)
Anyway, although the audio stream is 6 channels, what we are hearing is 2-channel stereo packaged in 5.1 @ 448kbps.
That means only 149kbps is actually being used, the other 299kbps is wasted on dead air. (AFAIK Dolby Digital is discreet CBR channels and doesn't share or conserve bitrate.)
That is unfortunate.
