Ok, I understand very well.

Ok, I'll test another media tomorrow or the day following tomorrow and
will report the result to the list.

No Media ID.

Keep in mind that these 2 media are in these _states_ because I try to
blank them with software:
 - one with "dvd+rw-format -blank=full /dev/cd0";
 - the other using "./cdrecord-wrapper.sh -v -blank=all dev=3,0,0".

Yes, I buy 2 packs TDK: one contained 5 DVD-R, the other 5 DVD-RW. So,
I can confirm... :(
