Using Media Center and the default microsoft codecs/decoders, we have seen issues with almost all dvds where the initial dvd menu will appear and work perfectly, but when you go to a submenu such as a chapter list, special features, etc. Half of the screen will be the initial menu and the other half will be the menu I'm trying to bring up. The cursor is still correctly located, but none of the text or images match up. In some cases where I find what I need and get into the movie, if I go back out the menu appears correctly? Anyone else had this issue?
