codecs
 

when i started using limewire i was able to download most everthing, now when i try to download any movie or some video, i get a message that says i don't have the right codecs to play my file! i tried several places to download codecs and even though they download correctly i still get that codec message. any help would be greatly appreciated!!!!!!!

Have you tried simply using an alternate player?
Try VLC (->link).

As a side note, are you sure you are installing them correctly? Installing a codec isn't simply downloading it: you also need to put it to the adequate place.
