I'm glad to hear that people are enjoying the mix. At some point I may make a list of all the work that was done on it, so I can show that I did actually improve it compared to the previous version and wasn't just harping on about insignificant details. ;)
I just posted this in Harmy's thread, but I'll put it here too since it's relevant:

. . . since the 5.1 mix was created by upmixing a stereo track and is not truly discrete, downmixing it back to stereo again is inadvisable. There is a distinct possibility that doing so could cause phase problems, most likely heard as distortion in the high frequencies, which obviously is a less than optimal listening experience. The most obvious cause of such phase problems would be the fact that the surround channels (which contain a certain amount of unavoidable crosstalk from the front) are delayed by 10 milliseconds, and definitely won't align properly in a downmix. Add this to the fact that Dolby Digital decoders may drop the LFE channel when downmixing, in which case the main benefit of the 5.1—namely, the added bass content—would go unheard.
So if, for example, you will be listening to the movie on headphones, or any system without a subwoofer installed, then the two channel version of the 70mm track could make for a more optimal listening experience.
