It nearly is inactive. Once it was a common discussion forum for
free burn programs. I fear that we have no Blu-ray video experts here.

Afaik, mkisofs can prepare an UDF hybrid for DVD video players.
See its option -dvd-video and the examples in the web.
There are tools like http://dvdauthor.sourceforge.net/ which use mkisofs
to produce the UDF filesystem around their video specific files.
But for Blu-ray there seems to be no similar tool.

You don't need pktcdvd if you burn the medium by a burn program.

This driver is needed only if you want to write by normal POSIX I/O
functions to formatted CD-RW or DVD-RW. Its job is to bundle the write
operations to full 32 KiB chunks, which the media in question expect
as transaction size.

DVD-RAM, DVD+RW, and BD-RE have a transaction size of 2 KiB. They can
be written by POSIX means without the help of pktcdvd. I.e. you can format
a filesystem on them and mount it for reading and writing.
(Only problem is that it will be darn slow, make noises, and wear off
 your BD drive quicker than burn programs would do.)

I would expect mixed results, depending on the age and maker of the player.
If you need to have the BD play on arbitrary players, then i expect that
you have to use a Blu-ray authoring tool on MS-Windows or MacOS.

Have a nice day :)
