JK you find that file it was called like _cd or something, it's on the original disc. Copy it over. You can also copy over all the cutscenes to your hard drive in the proper file structure to view those too. The problem occurs when you go through the second half of the game, then you need to copy over the _cd file from the second disc or it'll goof up (unless you skip all cutscenes). You also miss out on the CD audio music...
MotS was different, it basically required a CD "crack" (made by some third party folks and completely unsupported by LucasArts... and sometimes with a virus on it, scan every file before testing!). And of course you missed out on the music and cutscenes (that ones that played in that SCN format that MotS used for the pre-rendered ones).
