I am missing something. How can this only apply to -R media if you say it is on a DVD-Video?

I am aware of the potential inclusion in on air broadcasts and the shut down of the manditory hardware requirement last Summer, but I have yet to see this on a pressed DVD.

BTW, most of the drives I listed above were using codeguy's firmware or L&D's so I skipped listing it. The interesting question will be if it is firmware dependant, will it be removable.
