New Onkyo Pro 885 software update....

I am wondering if anyone has a latest software update for the Onkyo Professional SC-885 processor or where I can get a link for one? I am concerned about onscreen issues through HDMI switching in and out....I am also concerned why I cannot get HD Master Audio or DD-Plus through the PS3. The PS3 has a Bitstream/Linear PCM option. I want to utilize the processing in the Onkyo and not the PS3...THX
