I recently bought a Sony DRU-500UL (external) by using FireWire interface.
After burning many DVD-R (Imation 2x, Pioneer 2x, Verbatim 2x) with Nero 126.96.36.199, I remarked that my LiteOn XJ-HD165H with the firmware CH11 takes 20 to 25 seconds to analyze the DVD-R after insertion.
I don’t have this problem with the DVD+R & the DVD+RW.
The second point is that when I insert the DVD-R in the Sony (the writer), it regconizes the DVD-R within 5 to 7 seconds.
Is my LiteOn in trouble ?
(I just bought it 30 days ago)
