I upgraded to Win7 Pro X64. Now, when using media player, I have no sound when playing a MPG file and sometimes the video will jump forward and go normal with still no sound. All other types of files work OK, and with sound. I noticed at the bottom center of player where you have a big Play/Pause button, there is also a directional left and right buttons. The left button is pushed down and will not release. Called MS-support, talked to them and after an hour and a half, they said to find another media player and use it, enstead of MS's media player. Support marked case number not resolved. I have formatted hard drive and re-installed Win7 3 times now with same problem each time.
Need some help, Please!!!!
