Okay, I'm having alot of troubles with this codec. I have a really good quality Xvid I'm trying to play but I'm getting nosound in mplayer2, it crashes windows media player 8 and winamp 5.x. I may have the nimo pack and I know that will cause problems but I can't find anywhere to uninstall it. I've downloaded the AAC codec and installed it from multiple websites in the hope that it might get me the sound I want. I'm also sure I can play ogg files, so that isn't the problem. Any idea what I can do to clear this rat mess of codecs? FAQ's and searching on forums just isn't working for me, believe me I tried.
