The x86_64 DVDs are bigger (fuller). CDs and DVDs work like old

It may be that the DVDs are spinning fast enough that the flutter
present at the outer edge of all CDs and DVDs when they're spun fast
is hosing the drive's ability to see the end of session mark. This
is more prevalent on DVDs as the data density is greater than on
CDs.
but it's the "fuller" 64-bit DVDs that are the readable ones -- your
logic is backwards.
Whoops! Yes, now that I reread your message, you're right. Ok, I'm
stumped other than BIOS settings.
