I've been using Any DVD and DVD Clone for some time and have never had any problem. After watching a movie I had copied onto my hard drive I put the computer into Standby. The next day I tried continuing the same movie but could not get the sound to work. Now I get no sound when I try to play a DVD or watch one I've burned on the hard drive. It works fine playing a CD or an MP3 on the computer, and even plays sound on DVDs I've copied onto my hard drive using DVD Mobile. I've rebooted and even upgraded to 6.0.9.0, same problem. When I disable Any DVD and try to play one I get an error message telling me "Windows Media Player cannot play the DVD because a problem occurred with digital copyright protection." Any ideas? I made no changes to the computer. Thanks.
