Hi, I currently have the latter version of the 9104-3 firmware and whilst it clears up some issues, some freezing and picture corruption on certain discs still remain. I've got hold of the non multi region version of the 9104-4 firmware, but before I tried that I was wondering in anyone out there has the multi region version of it. I believe the firmware revision is. DRV 3-16-0 ESS 9104-4 I can't seem to find it anywhere out there, any help would be much appreciated. Mac.
