I am facing a severe issue in my Vista MCE. I have a huge collection of mp3 and dvd movies in my computer hard drive. When I play music using Windows Media Player the music plays very slow. It lags in middle many times. The video is facing the same problem. After playing for sometime the video hangs in the middle. Then it starts automatically. The performance is getting extremely slow. How can I increase the performance of my Windows Media Center PC. Thanks in advance.
