Possibly the above file tree structure on hdd isn't complete as on the
BD .........(should include BDMV ...)

I add some more info to this part:
Re. BD-R bit rate
BD drive speeds/Data rate
DV: 25 Mbps (compression 5:1)
DVD max 9.8 Mbps (SD, MPEG-2/MP at ML)
HDV 1080i: 25 Mbps (MPEG-2/MP at H-14)
info of interest from Vegas Pro manual (2020):
Media File Settings for Blu-ray Disc Projects
You can burn Blu-ray Disc projects to BD recordable discs using the BDMV
A 25 GB single-layer BD recordable disc can store approximately 3 hours,
42 minutes of AVC video (15
Mbps) or 2 hours, 15 minutes of MPEG-2 video (25 Mbps).
A 50 GB dual-layer BD recordable disc can store approximately 7 hours,
25 minutes of AVC video (15
Mbps) or 4 hours, 31 minutes of MPEG-2 video (25 Mbps)
You can store large amounts of standard-definition MPEG-2 video on a BD
disc. (page 459)
