[Rant]Nimo is crap imo, I alway hear about people having problems with Nimo, Tsunarmi and a few other packs. But people oftem jusy dont listen they go ahead and install Nimo, it works for a little while and then "Wah Wah Wah its not working properly"[/Rant]
A big no no that people do that they dont realise is wrong is installing other codec packs on top of others without 1st completely removing them.
The codec pack I use and have never (
never ever) had any problems no matter what PC I have installed it on is the
Ace Mega Codecs Pack
A neat thing about this codec pack is when you install it, it has a little built in program called "Agressive Remover" which will completely remove all existing codecs on your PC before installing these new ones, oh and btw it installs all codecs (there are a lot) and depending on what version you go for - you may get many useful utilities too.
