After reinstalling my Win XP, tried to play a music video DVD but got a black window with a message: "The media player cannot play this DVD because a compatible decoder is not installed on the computer". When I tried to play a pre-recorded music CD the itunes played it perfectly, yet I could not get the itunes to play the DVD. I never had this problem before I reinstalled the XP and have done all the updates. Please help.
Thanks.
