Both version 1 & 2 have the custom Dolby Digital 5.1 audio so why would you make up a shitty Vegas upmix version? just rip the audio off the discs you got,these sound way better than what Vegas produces,Vegas 5.1 upmix sounds very echoey not to good at all,at least not to me.

and if your wondering, the only difference between version 1 and version 2 is the subtitle placement,in the first version it was down in the bottom black bar portion,in version 2 it is in the lower portion of the video,in my opinion where it should have been to begin with,and also version 2 has the "Magic Tree" fix for ESB,there was a section of the video that got very jerky\stuttering during this scene in version 1(wish I would have caught that before uploading)anything else just ask.
