Ok. The media I bought are as follow:
 - TDK DVD-RW single-sided Data/Video 4.7GB 1-2x;
 - TDK DVD-R  single-sided Data/Video 4.7GB 1-4x.

Is there anything wrong whith these types of media? Advices?

Here are some informations about the report from "dvd+rw-mediainfo".

1/ Two new DVD-RW I tried to blank and which are now _not_usable_ says:

It is interesting to note that the only media to report correctly its
Media ID is a new (never touched) media. Even on the correctly burned
DVD-R media the Media ID is not provided by "dvd+rw-mediainfo"...

I don't think my problems were related to the quality of the TDK
DVD-R/RW. What do you think?

Thanks,
