I just bought a Denon ADV-700 DVD/Receiver which is wonderful but unfortunately the dvd player is region locked.
According to this thread:

A hack exists to make it region free, but it requires a file which might be impossible to find ... In the thread it says to mail an address to get it, but this mail account doesn't exist any more...

It's a long shot, but is there perhaps a tiny, tiny chance that this file still exists somewhere, or should I just give up? I've mailed Denons custom support but so far no answer.

Thank you,
