@ Phyllis
Yeah, my notices were more reminders - and not actually meant as manual 

I would suggest to make three sections in the manual - reflecting each 
common, legacy tape-based and current file based digital camcorder format.

1. DV to SD-Blu-ray video (re-encoding video to mpeg2, re-encoding DV 
LPCM audio to Blu-ray LPCM)
2. HDV to Blu-ray video (copying mpeg2 video, re-encoding MP2 audio to 
LPCM or AC-3)
3. AVCHD to Blu-ray video (copying H.264 video and AC-3 audio)

At least 1 and 2  bdwrite to create the udfs image to burn. And as most 
users nowadays are expected to install Cin-GG from Appimage, it will 
need an intro section how to enable bdwrite by mounting it from the 

I can help to suggest/edit/reading manual texts for 1 and 2 - with the 
format I have tested. Possibly we should not stress to get it finished 
this month(?)
And possibly we three should email this process directly outside the 
mailing list, or just post the finished text, you decide?
