Okay, I was able to update yesterday to FW version 1100-6103-0100. Unfortunately it didn't fix the problem I'm having, which is that the video output doesn't always work on Main when the receiver is turned on from standby and I have Monitor Out set to Both. I have to change it to Main to get the picture and then, after a few hours maybe, I can switch it back to Both. I was hoping the FW update would fix this but the problem's still there. Does anyone have any ideas? Is this a known problem with the 515 or do I have a faulty unit? BTW, Network Standby is off.
