I have some problem with Windows Media Center. When I try to run some video play music I am getting a error 0x80020009 and it stopped working. Later on there is a wmp.dll not register message. I found this in event viewer and yet not able to figure out why this error keep on appearing. I am not able to find any reliable solution to deal with the problem. I tried to run windows update and even checked for some patches. But there is nothing that is working and still it is getting crashing. I am sure this is some kind of codec issue.
