OK, another update.
I changed the menu from the imported v6.1 file, to a menu that's available from the v10 that I upgraded to, and I got past the 8007000e error I was getting.
But, I got another error.
I got a Failed to start the image writing operation Error while burning image error. That could be b/c I've been re-using the DVDs from the failed attempts.
Ill try again with a new DVD and see what happens.
Edit: Tried with a new disc, same thing happened.
