eric,
The things you mention here are not germaine to the subject matter at hand. DVD video is a file format readable and playable by set top players, and how its stamped or recorded to disc is a different matter. The fact that you can copy and play (on a set top DVD player) the TS_Video file (not copy protected of course) from a replicated (stamped) DVD to a DVD-R is not an accident, and it should tell you something. More importantly, as Ken pointed out, Susan has been left with the impression that its okay to print the DVD logo on her box.
