Both Ricoh (see below), but they did change properties of the DVD, while the
labels in the slim box are IDENTICAL. This is the only thing a potential
buyer can rely on, of course I can't take 'DVD identifier' with me in the
shop...

Yes, this is very interesting afterwards, but how can it prevent one from
buying beforehand?

First of all, the good news is as follows:
because I couldn't reach the vendor (busy), I decided to have another go
against all odds, but this time using another speed. According to Nero I
could use speeds up to 8, so I decided to go somewhere in between. I used 6
speed this time, burned and verified the DVD. This time... it seems I can
play the DVD on all DVD players! Praise the lord.
Gosh... at least I'm happy to have found a work around and I hope it's only
going to cost me one coaster. Of coarse I'm going to stay with 6 speed for
these DVD's, but what will they have been changing behind my back next time
I buy DL DVD's??
And I emphasize that the Nashua pack (10 pieces) was IDENTICAL and still
states 2.4X!! So one should expect all speeds to yielding working copies!!
Below I have added the DVD Identifier report for the old pack (first) and
the new one (second).
