DVD-Audio watermarks

jjolson, may be right about there being three different types of DVD-Audio players. The method I described here works in two out of the three types for sure. If your attempts at cloning do not work in your player, try another player. When I get time I will try more players. We are talking about the contents of the AUDIO_TS folder, If this folder is empty you do not have a DVD-Audio disc.

 

I never knew about the Roy Orbison not having VIDEO_TS. Afaik DVD-A discs MUST have VIDEO_TS lossy content, otherwise they can't legally display the DVD-A logo. I don't have the Roy Orbison so I'm not sure if it does. But all HDAD discs are examples of this - on one side there's the VIDEO_TS and the other the AUDIO_TS. The "DVD-A side" is technically out of spec for DVD-A, but it's ok since it doesn't carry the "DVD-A" logo anyway.
