This is not related to ARC.
You are having Copy Protection problems in the HDMI handshake between the Anthem and the display (most likely since it effects multiple sources) or between the Anthem and the sources (less likely).
First steps. Power down everything. In addition, turn off the Anthem using its back panel switch. Now gently reseat your HDMI plugs (both ends). The most likely issue is that a plug has come a little loose in the socket. This is particularly likely if you reached around back there to attach and detach the serial connection for your ARC setup.
Now power up and see if things work better.
If that doesn't do it, consider what might have changed related to cabling since it last worked correctly.
If you just recently updated to a V1.3x software version in your D2, understand that its current HDMI implementation takes a lot longer to sync up properly when you select a new source or change video resolutions from the same source. Maybe 10 seconds or so.
Anthem is working on new HDMI code that reduces this back down to a more reasonable 2 seconds.
Basically the current HDMI implementation is doing a lot more retries than it really should have to do.
