Hi,

This is not the fix for Bug 381074 but rather the cleanup after the fix
plus a courageous move to allow BD media for "VideoDvdDoc" which talks
of the typical filesystem structures of Video DVD. E.g. directory "VIDEO_TS".

The decisive bug fix changeset is
 
https://cgit.kde.org/k3b.git/commit/?id=329c969be1dbc3455d65925bcad32f4df3a5b428
where Leslie and i would still need to discuss the outdated comments.

We'd both need to practice with git in order to keep the experiments
away from the final fix.

----------------------------------------------------------------------
As for the courage in above changeset:

The format requirements for Blu-ray Video differ from DVD video.
With much caution read and compare
  https://en.wikipedia.org/wiki/Blu-ray#Data_format_standards
  https://en.wikipedia.org/wiki/DVD-Video
and keep in mind that these requirements only apply to consumer electronics
(aka "living room") video players.
With general data storage or with video files which your computer can play
from hard disk, there is no need to use UDF as filesystem or to have a
"BDMV" directory.

I know of no free tool on GNU/Linux which would produce the prescribed
format for Blu-ray video. If K3B and its helper programs can do, i'd like
to learn a URL to which i can send people who ask for Blu-ray video.

@Leslie:

Maybe an amateurish idea, but how about you revoke all three new
"| K3b::Device::MEDIA_WRITABLE_BD". I.e. the two fixes and the courageous one.
Also remove comment "10" above the two bug fix lines. It is outdated now.

Then commit the two MEDIA_WRITABLE_BD lines in 
 
https://cgit.kde.org/k3b.git/commit/?id=329c969be1dbc3455d65925bcad32f4df3a5b428
as official fix of Bug 381074. Leave out comment "10" and the qDebug(),
of course.

If you feel still ok with the MEDIA_WRITABLE_BD in k3bvideodvddoc.cpp, then
better commit it separately.

Have a nice day :)

Thomas
