After holding off for the last 6-8 months, I bite the bullet and installed the latest firmware update.
My 4810 has been working fine without any issues so I was hesitant to install any firmware update. (If it's not broke, don't fix it rule.)
Installing the firmware update looked like it was going fine until I got a : Connection Failure message. Crap!! (I was even using a wired connection.)
Fortunately I was able to re-power and retry the update.
This time it finished installing without a hitch. Scared me to death as I just had visions of a bricked AVR.
Don't even know what this latest firmware update was suppose to do, but it's done and seems like it's is still working ok.
Did have one strange thing happen where all the sudden my 4810 AVR display info went from DSD Multi-Direct to Multi CH Direct when playing SACD's.
Was able to go into the AVR menu and change the surround mode to Direct and now it's back to displaying the correct info and playback mode.
As long as my 4810 continues to operate without issues (So far no NIC problems) I am very pleased with it's performance and don't really see the need to upgrade to a newer model any time soon.
