why does DVDA recompress my .m2v video?

Hi again,
still struggling with this 8mm to BD project.
OK so now I did a 25p master export of all the clips on the timeline to one big file, then stretched it to 24p with farss' timeline trick, reexported it for DVDA using the bluray 24p template ( which is 23,97 as default), resulting in a .m2v file.
Of course, all previously set chapter markers were off, but ithat's rectified now.
But when I now want to burn the BD, DVDA tells me it needs to recompress. Why?
The project is set to mpeg 2 and 23,97p.
Thanks for any help!

What compression are you using for the audio?
Do you have DVDA set up as a Bluray 23.97 Progressive format?

If you look under FILE>OPTIMIZE DISK

it will give you a basic idea of what needs to be recompressed.

Thanks Donald!

Even though the warning said the video was going to be recompressed, it was actually the audio and , so it seems, some of the menu graphics.
The original files have no audio, they are old 8mm films, so there was no audio exported or present at all. I guess DVDA needs to create an empty audio track all the same.

Exactly. It does need to create an audio track. And menu graphics have to be changed to the DVD format. Glad it worked out okay.
