I have uninstalled and re-installed divx 3,4, and 5. Also the entire nimo codec pack. With the nimo codec pack installed I can't play regular mpeg1 files. Without the nimo pack I cant play Xvid or AC3 divxs. Someone please tell me the process of installing the codecs. and maybe suggest a good player too. I am currently using windows media player 9 for my mpeg1's and powerDVD for my mpeg2's. And i was using power divx for my divx files. I now cant get the both to play without uninstalling the nimo pack everytime I want to watch and mpeg.
