uk, you insult me with you "novice mistakes"... =P

No, I made sure all my codecs were installed AFTER I upgraded to the new WMP (I got the new version when I re-installed Windows, then got codecs). The problem I see here is not codecs. The problem I see is incompatibility issues. Complete video files having the inability to play, or be deleted, unless through the Limewire library.

I'm not new to this sort of thing.. I'm quite bugged myself. I actually do tech support at my internet cafe. I just can't seem to figure out what could possibly be the problem.
