i have a 59DJ with 2.3 rev2 firmware and in combination with a Pioneer 111D it reads every DL backup I put in. It only reads DL backups AFAIK, movie backups on SL-media work fine though. Only tried TDK/Philips (both RICOH...).
The only two things that botters me is that the hacked firmware supports only drives till 59B and that I can hear the drive read the discs a bit louder then originals. I cant really describe the sound: its not clicking but something else (IMG:
