They wanted my unit for testing to figure out exactly what is happening, not to fix it. If one of the most popular assumptions is correct and this is an HDMI Handshake problem. The fix may be distributed to the rest of the Owners via a Firmware update.
As more and more people are reporting in here. The dropout issue is becoming evident via all modes of transmission (i,e, HDMI & Optical) and sources (Cable, Satellite, Bluray players) it may be a decoding bug with the processor. I don't know if that can be addressed via Firmware or not.
Perhaps if enough of us complain we may see Onkyo take a more proactive role and possibly offer to pay shipping both ways. They already agree to pay for return shipping in the standard Warranty. The above is part and parcel of why I am posting and asking folks to report their problems via the Onkyo web site.
Coming in here and describing the problems you are having is a good thing, but does little to further this issue with Onkyo. As they do not read or respond to these or any other non Onkyo forum. I agree they should.
Just trying to heard turtles here and build a larger contingent of people who are willing to document their issues on the Onkyo web site http://www.onkyousa.com/feedback_form.cfm
. There is strength in numbers.
