I'm not sure if PSXMC works with the PC version, but you can try and see: http://homepage2.nifty.com/~mkb/PsxMC/

Or, open your disk in Explorer; are there files ending in .STR? You can use an .STR viewer for those. I'm not sure what the PC versions FMVs are encoded as, I just know they're at twice the resolution and for that reason alone I wish I had access to them (also for chocoworld)
