Denon AVP-A1HDCI & AVR-5308CI Firmware Update*Anyone considering this update should proceed with caution as some AVP owners have experienced some serious unit freeze ups and operational issues. More info on this will be provided as it becomes available.*
[update] 08/10/08
After hearing about the success that AVP owners are having with the update here recently, I decided to give it a go myself. I'm happy to report that my AVP update was successful and went through without a hitch. The update took exactly 61 minutes. So it "seems" as though whatever problems were there before, may have now been corrected. After the update I tested the music streaming to make sure that was ok, it was fine.

How to initiate firmware update:
Turn off power of AVP-A1HDCI
Connect straight thru Ethernet cable from your router to the AVP-A1HDCI
Enter “Manual Setup” > “Option Setup” area of OSD
Select “Firmware update”
Do NOT use a wireless connection when updating firmware and make sure there are no power interruptions during this process. The update can take up to one hour which during the process will render your AVP-A1HDCI/ AVR-5308CI inoperable.
