DualDisc: troubles with 1620?

Hi… Just 'bought my 2 first DualDiscs… Talking Heads classics, Remain In Light and Fear Of Music… Second-hand. :slight_smile:

Problem: using Nero DVD/CD Speed, I got bad scores on both discs, juste the CD-sides (DVD sides scored well). :sad:

Before I get back to my e-bay seller and start yelling at him, is there any problem with that media for Benq 1620? I know they are thicker than normal mediums…

Thanks for sharing…
