I have an 805 since 2009, bought it second hand. It came with the "Premium Digital" 2.6 FW version.
I never had problems with the player or discs, but yesterday it started showing the 408bc504 reading error, Goodfellas and Aviator both stopped.
I cleaned Goodfellas (the disc had greasy fingerprints on it) and it got better, it played through the point it previously stopped, but later on it came with the error. Aviator didn't have any scratches, dust or fingertips.
Both discs played flawlessly before, actually all my discs have played flawlessly in the past and I have like 60 or so.
What should I do?
Clean the lens with one of those old DVD lens cleaning discs?
Update to latest FW? If so can I go from "Premium Digital" to original Onkyo FW? Where can I find the FW files?
