This information doesn’t seem to be anywhere on this forum, and I only found one obscure reference to it on the entire web, but it solved my problem and I wanted to share.
I have the nec nd-1100a and was trying to burn 4x media in nero. However, it was only being recognized at 2x. This is because the firmware has to be coded to read the ID on the media, which in my case was CMC MAG F01.
None of the hacked firmware’s have the fix to detect this (and other) newer media types. However, I did find a thread that discusses the fix, and you apply a NEC developed firmware, not one of the hacks!
