Are there any guides on replacing the video stream on a retail bluray disc? I want to swap out the video streams for the main movie and trail mix-up with the uncensored versions. I thought multiAVCHD had this capability but I can't seem to find it and tsMuxer won't let me select a name for the resulting m2ts file when I remux using the bluray structure, which messes up the playlist and clipinfo files.

So, from what I understand, BD Reauthor Pro (by DVDlogic) is the best option for what you're trying to accomplish. The reason I say this, is because over on rutracker, I see that being used to reauthor blurays more than anything else and the results are always satisfactory and have good reviews, on top of the fact that I can vouch for the fact that those are always good copies (haven't seen one messed up one yet)

the official link for the software is: http://www.dvd-logic.com/bdreauthorpro.php (there are pirated copies floating around, I'm sure, but this is the official site for it and that is the only link I'll provide as I am NOT supporting piracy)
