Nero CD speed discscan hangs up with some dvds

Hello,

recently I got a strange new problem with nero cd speed tool. With some of my burnded data dvds, the discscan feature of the cd speed tool doesn’t even start scanning but hangs instead. With other data dvds (same Verbatim media, same software, same writer) the discscan feature works without any problem.

DVD writer: Optiarc AD 7280S Firmware 1.01
Nero CD Speed several versions
Windows XP

Disc info of the same tool (nero cd speed) shows only some minor differences in the first line of RAW data, here the dvd where discscan runs without a problem:

Physical Format Information (00h)
0000 - A1 0F 02 00 00 03 00 00 00 25 EE BF 00 00 00 00 - …%…

And here the first line of raw data of the disc with which nero cd speed hangs up:

Physical Format Information (00h)
0000 - A1 0F 02 00 00 03 00 00 00 24 7E 5F 00 00 00 00 - …$~_…

By the way: both discs are perfectly accessible, VSO inspector tests both as 100% ok, nero cd speed disk quality reports no problems and a quality index of over 90 on both discs.

Anyone any idea?

Yours

Pete
