Someone on the Lucasarts tech support forum said he found a mod that eliminated the load-up screen using XML and it fixed his freezing problem at the main screen. (I've tried everything and if this works awesome) Does anyone know where I could get it?

I take it he was referring to the Movies.xml file. The first two entries are for the LucasArts and Petroglyph intro movies. You could edit this XML file.

Another way (easier if you can't extract the XML files) would be to create the following folders in your \GameData\Data\ folder - \Art\Movies\Binked\ (so you'd have the following - \GameData\Data\Art\Movies\Binked\). Then create two blank text files in the \Binked\ folder and rename them to LucasArtsLogo.bik and PetroglyphLogo.bik. See if that solves your problem.
