Back in 2016/2017 I rendered a 1080i hdv.m2t clip to BDAV, burned it on a standard BD-RE disc and then could playback it as a 16:9 Blu-ray video in a Samsung Ultra Blu-ray player. https://lists.cinelerra-cv.org/pipermail/cinelerra/2017q1/005830.html
bd_20161216-153642 ├── bd.m2ts ├── bd.sh ├── bd.udfs ├── bd.xml └── udfs Anybody knows if "BDAV" format listed below refers to BDAV disc format (vs BDMV) or to the m2ts transport stream format?

What I wonder is if also the following features are possible in Cin-GG (bdwrite and/or tsMuxer, ffmpeg tools):
I think you better ask at tsmuxer github/forum: There is plenty of bits to get wrong .....

Yes, possibly better. I will think about it.
Note: in this thread DV is Dolby Vision, not DV as dvvideo!
Dolby Vision isn't mentioned in the specification? I verified that my own DV25 file also has "Overall bit rate of 28.8 Mb/s. Here are the most DV mentioned lines from the Whitepaper: * Direct recording of DV contents from the DV terminal of the camcorder with no picture deterioration (option) * Taking advantage of the BD-RE drive’s high user transfer rate (36Mbps), the BD-RE Application Format provides an optional functionality of recording DV streams (28.8Mbps) to BD-RE disc via the i.LINK. * Direct Recording of DV Input. The recording format for the DV stream conforms to the DVCR digital interface standard (IEC 61883-2) (Fig. 3.1.4.2.1). The DV stream received through i.LINK is not re-encoded but recorded directly to disc, with aligning the beginning of the DV stream with the logical sector boundary, as shown in Fig. 3.1.4.2.2(a). * Figure 3.1.4.2.1: Data structure of DV stream (compliant with digital interface standard for DVCR)(525 / 60) (626 / 50) * Fig. 3.1.4.2.3 shows the directory and file structures. DV stream files are stored in the /BDAV/STREAM directory as are TS files. DV stream files have the extension “dvsd” and are accordingly distinguished from TS files. * Since the video compression method adopted by the DV format is intraframe coding, each frame in the DV stream has a fixed number of bytes (525/60:120,000byte, 625/50:144,000byte). * DV stream has a comparatively high transfer rate of 28.8Mbps, * As previously described, the BD-RE Application Format adopts MPEG2 and DV formats as its video recording format (recording codec). When MPEG2 is used for recording, each frame image of the content is coded into either of three types—I-picture, P-picture, or B-picture—and compressed and recorded. -------------- Terje J. H
