It's definitely an HDMI handshake issue.
The XBR's have (so I have heard) handshake issues with a lot of gear. Check the XBR threads for information and to see if your model is affected.
If you use a Harmony or other universal remote, try changing the order in which your components power on and/or adjust the device delays. That may help.
Since we don't know what was changed in the new firmware (thanks a lot for the support Denon), it's just speculation and antidotal evidence, albeit pretty reasonable, that this could have been caused by the upgrade.
Have you contacted Denon about your network problem?
