Scanning with LiteOn DVDRW SHM-165P6S

I purchased the LiteOn yesterday and burned my first DVDs today. The burning results are very good but Nero CD-DVD Speed doesn’t show me the jitters during the scan. The latest Test-Firmware and Smartburn are installed. Does anyone know what the problem could be? By the way: which speed is the best for scanning? 6x? Thanks

The cdfreaks forum standard is to scan at 8x with the 165P6S. CDSpeed will not show jitter with a Lite-On. You need DVDScan to measure jitter.
