A stupid mistake of my own. In the meantime I had manually changed the
Directory anme from BD to BD-Video :)
I rendered HDV to BD successful now, but got Aspect error both with None
and Scaled:
1) None (scale): a small 4:3 sqeezed image covering 50% of the VLC
display area centered, no cropping:

2) Scaled: full Hight 4:3 sqeezed image horizontally centered on the VLC
display (corrected with forcing Aspect 16:9 in VLC)

I meant video Copy of the compliant 1080i HDV.m2t mpeg2 was a "smart
render" in this case ;)
(There is also additional non-anamorhic 1280x720 HDV available)
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.
Yes, the standard compliant MPEG-2 for HDV.m2t source profile is here:
