I alluded to this in my description of DVD-R. Thank you for correcting
my description of implementation details, though. (Obviously, you
don't need a special burner, but you do need to buy specially-licensed
media.)

I don't understand this position at all for this context. Unless
you're doing work in particular fields for the recording industry, why
touch DVD-R at all? Doing so because "it's the official format"
doesn't really mean anything; the industry and market has been stable
for years, and upstream isn't going to switch out everything out from
under people using the format. (At least, not in a way that doesn't
screw over DVD-R users as well.)

I'm not saying you're necessarily wrong in that perhaps DVD-R might be
the more appropriate format, but you should give some better arguments
than "it's the official format".
