Not that it matters, it's just a question.

I am working on that ability -- to create a 1080p HEVC (UHD format) disc -- but I disabled that code for this release because I haven't tested it very well.The UHD standard also allows 1080p using HEVC. So that part should be available soon.
If you'd like to experiment with the capability to output 1080p to disc using HEVC into a UHD format, try adding:

UHD_V3_MODE=1

...to your INI file. I haven't tested it much, but I'm pretty sure it would only work in movie-only mode right now. Don't forget to reset it to 0 after playing with it -- as it will try to make normal BD backups into UHD format.

[Edit] Nope... sorry. I just ran a test on a 1080p source and, while it played, BD-RB failed to add the "--repeat-headers" parameter in the encode and FF/REW/CHAP isn't working (for 1080p output). I fixed it for the next release.
