Hello Bill,

My understanding about this issue is that the BCA read functionality is 
already mandatory by being requested to support Format Code 03h of READ DVD 
STRUCTURE command for DVD Read Feature.

Of course, DVD-ROM drive, for example, may not be able to read BCA on DVD-R 
disc. But it is not a problem.

If my undarstanding above is correct, I don't think we need to care about 
the products which are not MMC compliant.

Best Regards,
