Cheers Foxy.
MY WDTV Live SMP doesn't have Cinavia. Even if it were to be included in a future firmware upgrade (unlikely, as they've had plenty of time to do so but haven't) it's pretty easy to find & apply old firmware versions.
Unlike Blu-ray Players theese media players have no moving...
Foxy, I back up all of my discs (am I allowed to say that?) FOR THIS VERY REASON and have never had a problem backing up a Blu-ray.
A keep one copy on my HDDs at home and another safety copy on HDDs in my store cupboard at work.
