Stating that WMP "doesn't play well" doesn't give us much to go on. There's a whole slew of things that could be causing the problem. Which version of WMP? Do you have the latest Codec Pack installed? Have you tried any other media players such as VLC? Do you have a bunch of crap programs running in the background? Are you having problems with audio, video, or both? Stuttering or freezing? You need to explain what's happening in more detail & what you've done to try to fix it.
