Still a no-go for me.

The two backups I made work on my friends Samsung. Lucky him. I guess that's what I get for buying on launch day, lol.

Here's my specs for anyone that cares.
Drive: Hitachi 47DJ
Firmware: 1.1, Didn't work with 1.0 either
Burner: LG GSA-4167B
Media: Verbatim DVD+R DL Item #95014(easily searched in Google)
Speed: 2.4x on the first burn, 1x on the second(both worked in friend's Samsung, not in my Hitachi)
Gonna go buy a pack of Memorex and a pack of TDK media tomorrow and see if it makes a difference. Anyone tried with DVD+RW DL or DVD-R DL?
Edit: One thing I did notice is that it tries for about 7 seconds longer before it gives up and gives me the DDE.
