Actually the remastered is all the way in Dolby Digital. First run your game on a TV that's been hooked up to a 5.1 Dolby Speaker System. Then listen to the center speaker, next left, right, and finally woofer (the back speakers are optional and may not make as much sound). If you only hear music out of the center speaker then it is NOT the remastered version. If you hear music coming out of LR and the woofer then IT IS remastered. There may be an easier, more accurate way to check the iso's information but I'm not sure how. I suppose something like Hash checking with both versions would work but I have no clue how to do that.
