@raston , the divice does not hung when resuming from sleep, but only the Video out. I have the audio output via Optical and if you browse through the U9 with the remote, you will see that it is on. You can play videos, move in the menu etc. but with no Video signal. One thing that could have caused this would had been the HDCP, but according to the FW07 change log, they fixed it. If so, then this wasn't the issue or they did not fixed it properly.
