Xenosaga questions

[dataeraser]

hello. I know about the dvd-9 issues. I've found the site that has the xenosaga movies but how would i be able to replace those with the originals? would i use an iso extractor program like iso buster or winiso to extract the image from xenosaga, then just replace and remake the iso again? The site is below.

Why would you want to replace the movie files?
