I have reverted my Egreat A5 to FW 1.1.0.7 because of the stuttering on DVD ISO and at present they are playing a lot better.
What I need to know now is how do I disable updates until Egreat have sorted the problem out. The player has already updated itself because I pressed the wrong button once. Each time I switch it on I get the update screen but the buttons at the bottom that allow you cancel or continue are missing and I believe there was a box that could be ticked which allowed the update to not be shown again, this is also missing.
