I tied to rip a Firefly BD to my HD but AnyDVD reported an error,read error from the BD+. I upgraded to AnyDVD to version 6515 and it ripped. Problem is when I backup one episode to a DVD+DL it plays with a severe stutter on my Sony player and also my computer. The m2ts file plays normally on my computer. I'm guessing that the BD+ is not being completely removed? I see there's another new AnyDVD update,6518,I download it and try again.
