I tried to burn a BluRay DVD in the usual way with MEP16. The burn progressed part way and then shut down, saying it was aborted, saying something about "wrong format", which was not true since I always use the same blank DVD-R discs just fine. I then shut down MEP16, restarted it, reloaded the exact same movie project to burn it again. This time, having not changed anything, when I clicked on the "Start burn process" icon in the"BURN DISC FOR DVD PLAYER" window a second small window appeared that said, "Should the existing file be used for the film, "(MY FILM TITLE)"? and below that were 5 button choices: USE USE ALL ENCODE ENCODE ALL and CANCEL. I clicked "use all" and the burn proceeded quickly and normally with no problems!
My question: How would I know which button to choose? What does each do? I can't find anything in any MEP documentation ANYWHERE that even mentions these choices or this window. I would love it if someone could educate me about this! Thanks. Feel free to reply to me at k9vet@rcn.com
