Samsung TS-E552U Extremely Slow burn Speed

Greetings Folks :slight_smile:

I’ve recently bought a TS-E552U DVD burner. I’ve found it’s taking 1h 20m (!!!) to burn a Single layer DVD-R disc 4.5Gb. The media is 16x rated.

This happens whatever speed I set in Nero6

I checked the drive in Nero’s CD-DVDR Speed and it’s saying 0.68x

The drive came with firmware US03. I updated to US06, but it made no difference.

CDR burns are OK.

I’d be most grateful for any help.

Cheers in advance
