<div> I suggest CinGG supports all valid
BD-formats, SD and HDV anamorphic included.
I am currently not rigged to test BD
1440x1080 with BD player and TV, but I think
I did test it previously on a PC display
(can possibly test it later by opportunity).
<br>
If not other project reasons, I basically
don't see why to up-convert and store more
pixels on the medium, if and when the
1440x1080 format scales fine to 16:9 by the
player/TV. Just did a simple succesful test
with VLC now.<br>

It would be fine if Create BD also could be
extended to offer compliant mpeg2 video and
video copy (smart rendering) with separate
AC3/PCM_bluray audio (ref. Create BD video

I meant video Copy of the compliant 1080i HDV.m2t mpeg2
was a "smart render" in this case ;)<br>
(There is also additional non-anamorhic 1280x720 HDV
available)<br>
<br>
I saw the tsmuxer button is also available, so possibly
AC3/PCM then can be muxed together with MPEG-2, similar
like I did with FFmpeg in my previous "Preserving
Camcorder Media" chpt 5 page 17 (23)? Just keep (copy)
the mpeg2 video as is and transcode the MP2 audio to
AC3/ PCM.<br>
