Mine suffers from the no audio problem. I will have to switch between sources to get the audio back. Happens once in a while. There have also been times when the unit appears not to respond to the remote, but I am not sure if it the 970, or something else.

The 970/990 and the Oppo are a great combination. I have a Motorola DVR with DVI, an Oppo with DVI, and a JVC SX21 with DVI. I have no desire for HDMI as everyone seems to have issues. I have had no problems with DVI.
