I was wondering if it was possible to rewrite a part of dvd-handler to
use dvd+rw-mediainfo instead of growisofs to grab the freespace on a DVD
media.

That is, because I didn't find a patch for dvd+rw-tools 7.0 (which I
have installed), and also, if we can use dvd+rw-mediainfo, we would need
no patch!

Is the information here good to extract the 'appendableness' and
free-space of a DVD medium ?

Also, mediainfo is called already by dvd-handler (although perhaps not
at the same moment ?)

thanks

Debian has dvd+rw-tools v7.0-7 in testing, there must be a patch in
there for it and they distributed them with the patch.

I've reworked dvd-handler, and it now works without any patch. It uses
dvd+rw-mediainfo to grab information about the space left on a DVD
device.

As someone already pointed, there is no error handling when there is
*no* media in the drive.

See the modified dvd-handler attached (from version 2.0.2).

It might need some testing, but it works here.
