pac files? QuickBMS script?

[NH_97]

So, I'm currently watching NewLegacyInc's 24/7 Mode Stream, and got curious if it was possible to extract some of those image and audio files used in those modes(the ones I was particular interested in are the ones from the Side Activities, like the "Hero Movie" & "Villain Movie" that show the Superstar holding a gun/sword9, and I'm absolutely clueless when it comes to this stuff, but thus far I managed to get the "Xbox Image Browser" working, and access the files from a Xbox 360 Version ISO. So I can extract them with out any issue, but they are ".pac" files who I'm unfamiliar with. Apparently, I can extract content from those filees using a tool called QuickBMS, so I downloaded that, but now I apperantly need a specific script for SvR 2008, and I couldn't find one. So is there anyone here that has one?

If not, what would be an alternative way to access the images from the .pac file?
