I noticed advanced codecs, specifically DD+, maybe others as well, have stopped working on my AVR since 9.0.0. I have some test videos that does play just fine, but almost all the content that I did watch prior to 9.0.0 upgrade now doesn’t bitstream correctly. The AVR keeps blinking surround on/off, like it can’t sync with the signal. I wanted to go back to an older version to verify, but apparently someone thought it was a good idea to nuke all the previous releases.
