Everything *was* working fine after the upgrade for a week or two, then out of the blue the machine wouldn’t play MKV files, stating “Unsupported” when I’d previously been able to play them. I “Reset to Factory Settings” and the MKV would play but now all YouTube screens simply say “No Content” or “Unknown Network Error”. There’s nothing wrong with my network and all this was working fine.
Another Factory Reset, no dice. Reboot, no dice. Pinhole Reset, no dice. It’s not a good sign when most customers regret upgrading to the latest firmware.
