I don’t think anyone can answer that until you do it. What you’re describing is the same thing as AVCHD discs (Blu-ray format on DVD media, which work on some players, but not others), but in reverse. You’re making DVD format on Blu-ray media. I’m assuming, like AVCHD, some players may understand what to do with it, but I wouldn’t count on it.
Springing for some writable DVD media would be pretty painless and would always work.
I see I see, Thanks for the patience and the reply!
