On a Windows 7 Home Premium machine I can't play DVDs (commercially produced) with either Windows Media Player 12 or Windows Media Center. I can play video files (.avi or .wma) fine. I can also play DVDs using VLC and Nero 9 Showtime, though no sound on Showtime.
I have tried installing Shark's Codec pack and the k-lite codec pack for Windows 7 but no change - have uninstalled them after each trial.
I really want to use Windows Media Centre as I am using it for all other media-related activity (have HD Homerun tuner).
I can't udnerstand why codecs are not shared between apps - shouldn't they be like printer drivers and common to all apps??
Can anyone suggest how I can get WMC or WMP to play my movies please?
