My Windows Media player no longer seems to play dvds. I've never had a problem before but it's coming up with an error message: can't play dvd because a problem has occurred with digital copyright protection. I've never had this prob. before and some of the dvds I try to play are quite old. Anyway, I presume I need to update my codec? - What do I look for and is there freeware for this? Also my nero dvd (showtime) player has never had sound, is there an update/plug-in I can get to rectify this? I did look at your play-back probs. forum, do I just need to do what is suggested there to make my media player work properly? I downloaded cliprex ds dvd player originally to get windows media player working. I have just uninstalled and re-downloaded with no difference.
