Yeah, the 2004 master is full of stuff like this.

Also, I figured out, that if I remux the file as m2ts instead of mp4, it renders ok. But the m2ts file doesn't work properly when editing - whenever I try to move to another frame, the whole program freezes for like a minute before showing the frame, so it is unusable that way. But I was able to just import it on the timeline and render the first five minutes of it as lossless avi and then use that to edit the first five minutes of v2.0, so I should be able to simply use the m2ts in Premiere to render the lossless AVI that I should be able to work with perfectly and its size should stop being a problem soon, thanks to Troyig88.

Oh and Pheran, thanks for that nice post earlier. I was so preoccupied with this whole rendering problem, that I completely forgot to answer :-)
