Ok have done some further investigation and when loading the original game in XBC it shows bytes used to be 151 MB. This is way higher than I would have expected. Isn't it usually around 5 MB? Something tells me the video layers are in a different structure in this game, causing more (and invalid) data to be included in the video layer. But then again, I'm no expert on this type of thing.
I have also run the final rip through abgx360 and it tells me that stealth is fine, video is fine, DMI and PFI are fine. Of course, when it tries to connect to the internet to get a valid valid ini file there is none there because no one has uploaded a valid one yet (I guess because it only got released today). I'm using the latest software for all programs and have done may backups prior to this. In fact, just did one a couple of days ago with no problems.
So while abgx360 says it's a valid rip, XBC and Schtrom say it isn't and point to an invalid PFI and/or video. I'm at a loss.
