Intenso blanks like Russian Roulette

Greetings !
I had now bought at a distance of 3 Weeks 2 25er spindles these blanks (from various suppliers) and have to say hands off!
The first 25er Spindel was fine, only 1 failure when burning Xbox360 backups had, at the 2nd spindle but I could just 6 use of the 25Rohlingen ... the rest are now moved into the bin after 9 failed attempts in a row I got it then abandoned. Immediately after Media Markt and went 2 10er spindles Verbatim DL buy blanks and lo and behold everything works fine again. I burn with my Samsung SH183A burner and have the latest firmware SB03 uploaded.

Among the errors of the Intenso I can do something more accurate to say, 3 blanks are right at the start before an error causes before ever 1% was burned ("Set L0 Data Zone Capacity Failed - Reason: Invalid Field in Parameter List" So direct error in the first Layer. The frequent error, however, was particularly annoying to 100% Wurd burned, then either at closing or track when finalizing disc a nice error so that neither my PC still a DVD player or an Xbox were able to read the DVD ... ..

The spindle has taken the trouble was, incidentally, as a previous speaker said already stocked with Intenso blanks with the Media Code: RICOHJPN-D01-67.

My personal opinion (and based on my hardware, of course): Never again Intenso, I stay with the more expensive Verbatim! because ca 20euro is spend on then 6funktionierende Intenso blanks still more expensive than 35Euro for 25funktionierende Verbatim blanks! ;)
