So basically, once HD-DVD recorders start showing up, mastering house not setting VID (leaving it all zeros) would mean that home bit by bit copy of that particular disc in an encrypted state is possible (assuming that the protectred areas on the HD-DVD-R or equivalent media would have the BCA and friends all zeros, of course). And given how easy it is for consumer to create a fully decrypted backup, plus lack of long term problems with decrypted backups (inplying that consumers that would make backups of their media would chose to make decrypted backups), it's not as major an oversight at it might seem.
Hrm.
Thank you for clarifying.
BTW, this question came up when I was looking at "Relentless Enemies" - it has an all zeros VID but is AACS protected.
