This is the normal behaviour and no problem at all.

The same also goes for all 162* DVDRW drives. :frowning:

Normal…?, everything is relative. :wink:

It’s for sure giving you problem if you have an old (1-2x) DVD-RW.

As a sidenote. Latest NEC and Lite-On/Sony DVDRW’s are able to burn -R/-RW’s at rated 2x speed.
