Nero CD-DVD Speed Problem

I use the latest Nero CD-DVD Speed v3.30 but have always had problems doing any tests with Playstation 2 originals and backups.

Is it because they are UDF 1.01 format?

The transfer rate (RPM) test works in DVD Decrypter with PS2 discs.

XBOX backups work fine with the same media doing any DVD test in Nero CD-DVD Speed.
