My computer has recently become very penickerty when playing DVDs. Until the other day, it would play a DVD on anything I wanted, Windows Media Player or whatever. But now when it reaches the DVD's menu screen, it gives me the 'Windows Media Player has encountered a problem and needs to close' dialogue box. It also does this on a program I downloaded, although the player stops responding at the same point. The only program seemingly able to play the DVD is the 'Dell CinePlayer' that was pre-installed on my system.
I don't have a problem with this, but I defaulted WMP (11) to play DVDs, and have no idea to undo this and default CinePlayer.
