[Dvd-devel] A case where another free software works better than dvdrtool

[Julián Muñoz]

This is a report from someone who posted me (as I ask on the dvdrecord
web page) that he finds cdrecord-dvdhack to work better than dvdrecord:

Hardware: Pioneer DVD-RW DVR-104

dvdrecord output (dvdrecord fails to write):

# dvdrecord -v dev=0,0,0 blank=fast -dao iso.dvd

Manufacturer is unknown because of the orange forum embargo.
As the orange forum likes to get money for recent information,
it may be that this media does not use illegal manufacturer coding.

So, even cdrecord-dvdhack complains that it cannot determine the media
size but it still proceeds and writes the disk out fine.
