Hi again,

After some investigation:

The DVD-R File Systems Specifications relay on a subset of UDF, so mounting
is possible in every case. But the naming conventions for the content may
differ. Since convergece does not own the DVD-R File Specifications for DVD
Video, I can't give you a 100% reliable answer to this problem.

There also other Video Specifications for Recordable, Rerecordable and
Rewriteable Discs than for Read-Only Discs. convergence does own the
specifications, but we're bound to a NDA. The only statement I can make on
this is: The available Open Source DVD Video players will not play anything
but DVD-ROM Video (until someone hacks the things together ;-)).

AFAIK libdvdread uses the UDF module developed by convergence and released
under the GPL (or a part of it). If nobody messed the things up it should
work :-).

Bye... Szymon.
