I have amd athlon 64 x2 4800 and 2gb ram so decent spec there, but yet windows media player 11, is really slow to use and takes nearly 80% usage of my processor. At some points i just have to close it down its that bad.
Im watching a 720p video and burning a disc, not using more than 4%. Maybe you have some extra services installed or perhaps a piece of spyware thats pulling data from WMP.
I only play music via windows media player, my brothers computer shows like 2% cpu usage and hes got windows media 11 and a lower spec computer then me. Dont know whats going on?
I had similar problem with MP, where any video film i would play would stutter and slow down and even go out of sync, i tried to reinstall but no go, i tried a few other things but since it was on a 8 month install of xp and things in general were starting to cause problems i decided to format to fix my problem.
Anyway, have you tried to uninstall and reinstall mp11 ?
