Unable to use Nero CD Speed on non-originals

I just tried to use Nero CD Speed (CD quality check) but I get a “read error at 00:00:00 (code 031100)” The error occurs at diff times for all burnt cds (but always near the start)

I tried a blank cd and an original cd and they are fine.

I tried all diff test but still the same.

I also tried it in my Hitachi GD-2500 DVD and my Lite 32x burner.

Any ideas?

Any chance that the discs are really that bad? that error usually occurs when the disc is unreadable. Barring that, try re-installing Nero.

The discs work when I play them and CD Check finds no errors
