Reposted under the correct topic. Please disregard - well... i guess you already have - Sorry. I have WM Player 10 and I'm not sure if I have WM Services 9. What is WM Services 9 and what's the difference? Is WM Services 9 needed? and is it a necessary componet to MP? Is it included in XP SP2? I may have everything I need, but just don't realize it. With a few exceptions, MP works OK - just need to tweek it a bit. But, I'm wondering what this may have to do with the few issues I currently have. Media Portal getting better all to time. Excellent work!!!
