Dark Jedi,
I just checked out your V3 sample on my 5.1 system. The picture quality is passable (I know it's just rough, and it is from the GOUT after all). Hairy Hen's 5.1 mix is the star of the bunch though (it shows as 3/2.1 on my player). It sounds very full compared to all the others, even when my receiver tries to upmix them to 5.1.
If I may make a humble suggestion, I would recommend you make Hairy Hen's 5.1 track the first track. I'd hate for someone (who doesn't know how to change audio tracks) to judge this disc by the default mono mix.
Maybe this:
track 1 - '77 DD 5.1 upmix
track 2 - '77 Theatrical
track 3 - '77 Mono
track 4 - '85 Stereo remix (taken for Japanese Special Collection)
track 5 - '93 Stereo mix
That is actually the order in which the tracks were released.
