Did you ever get anywhere with this? Is there a utility you can share for identification? I am only unsure between a PS2 or Xbox for an iso. isoinfo says that there are no files.
Sure, if you really want/"need" the highest quality there is you can grab remuxes. But will be pretty big file sizes, so disks can be better in that regard.
But piracy is free so...
some bluray rips are kinda crappy, remuxes are a more safe bet, but i usually don't have trouble finding a good rip, there are certain groups to avoid and some to look out for
