I can open an issue on their github, but just to be sure we're talking about
the same thing: I already have a directory containing a BDMV subtree (and
CERTIFICATE). I don't know if anything needs to be modified during the burning
process, but as far as I'm concerned, I'm just asking to burn that directory
onto a bluray that will work correctly on tv players. As things are now, I can
already burn everything using K3B and UDF 2.01, but tv players will not
recognise the bluray as a video one. Likely because of rule n. 1 here:
http://www.blu-raydisc.com/en/Industry/Specifications/PublicSpecs.aspx

So as I see it as a user, K3B should just do the same thing as ImgBurn: you
select the directories you want to burn, ImgBurn guesses from the tree
structure that it's a video disk and asks if you want to use UDF 2.5 and make a
video disk indeed. Then you press ok and wait for it to finish.

If you're talking about the actual creation of bluray videos from your own .mkv
files for example, then I think that's going to be much more complicated.
However, it's not what I'm asking for.

Either way, I found a mildly interesting forum thread here
http://forum.doom9.org/archive/index.php/t-141361.html detailing the binary
file formats (see frank's post). As I understand it, the burning program might
have to edit some files before burning them, depending on the medium type. This
is all new to me, but on another forum they refer to the same post and add this
comment: "So depending on whether you choose "Remux to AVCHD (FAT32/PS3
compatability mode)" or Blu-Ray that headers will be corrected. Currently it's
a 1/2 BD 1/2 AVCHD by tsMuxeR (see posting above with highlighting)".

So if that's the only thing the burning software has to do, and the rest is
just a regular UDF filesystem that udftools can create, then all the components
are there, or am I misunderstanding things?
