I think it really depends on what sceens you are going to attempt to extract from Xenosaga. I am pretty sure that the majority of the cut-scenes are actually rendered. However, I'm also sure that some scenes are definately some sort of pre rendered video though. For instance, when KOS-MOS uses the uhh...what was it? Oh yeah the "X-Buster" move, you can tell that is pre done. Good luck with the extraction.
