Not entirely true. I burned all my games with my NEC3540, 1W8 firmware and platinum / verbatim media. These all work flawlessly on my XBOX360 (samsung drive).
Yesterday i flashed a Hitachi 59D for a friend of mine. Used Maximus/garyopa 2.2 with revised bats. Well, the flashing went allright (thnx GaryOpa). Furthermore, this hitachi plays ALL my backups too (

) . This is the 1st time i see a hitachi thats able to read my NEC3540/platinum backups but i tell you, it did
So, i can confirm that (in some cases), NEC3540 + Hitachi is possible.
I too can confirm that my NEC 3500 can burn fully working backups for both Samsung and Hitachi. However, in the last couple of days I've encountered three Hitachis that
read those backups. I know one of them was a 59DH (that's what it said on the drive) and another was a 47-something.
I've been using Traxdata (Ritek?) discs and also a TDK disc. The Traxdata discs have worked on every Samsung
Hitachi except those above, while the TDK did work for all drives.
As previously said, the backup works while the original doesn't (it will with this FW update though).
