I just wanted to let you all know that I fixed the problem. I downloaded a codecs package (
Codec Guide: K-Lite Codec Pack and other useful stuff ) called K-Lite Mega Codec Pack and it seemed to fix the problem. While installing it it detected a broken or missing video file in System Shock 2, so I removed it since that's what it recommended to do. Hope this helps anyone else out who is having this same problem, and thanks again for all of your help!!!
*Edit* By the way, for those of you running a dual processor like me this may help to get SS2 running for you as well. I kept on working on trying to configure my processor even though it seemed fine for the game, but this really did do the trick. Good luck to you all
