I owned a Nec ND-1100A (OEM Dell-Firmware 10 GE) for about 2 years now & have been burning DVD movies & games on DVD+R that were fully compatible with my XBOX.
I bought a ND-3520A OEM through Newegg.com about a week ago, took out the ND-1100A and replaced it with the new burner. I burned a 2 DVD videos on +R's and they didn't work in my xbox. I must add that I tried them on my standalone player and my PC and they worked perfect.
I then removed the ND-3250 & tried the ND-1100A with the same type of DVD+R from the same pack I tried before, and it played on my Xbox with no Problem.
These were burnt from the same Image i saved in my computer and i checked the burnt dvd with DVDinfo pro, which said that both of the Booktype was DVD-ROM.
I updated to the latest firmware 3.04, for the ND-3520A & also gave liggy & dee's hacked firmware with no luck. Could another hacked firmware help this?
