SOURCE: TV not finding Digital Channels from Cable Box
We have Comcast and we plugged the cable straight into our Bravia, searched for Digital Channels and it found 131. We actually get all the HD channels that we had using the box, plus a few more. It's worth a try.
SOURCE: HDMI connectivity
I have the SA8300HDC STB from Time Warner. I get this error from my DVD recorder, not from my HDMI connection. I've read that the error is due to copy protection. The only solution I've read about has to do with a new Samsung Set-top box from TWC. Funny this copy protection error didn't ever come up with my old VCR connection to the HDTV. TWC apparently told a lot of people that the problem would be solved by a software update from TWC in October 2007 & then in December 2007. Guess TWC isn't sure what the problem is but everyone who has mentioned this Samsung cable box has reported success with their HDMI connection.

I had the exact same problem on a brand new Insignia 26 " LCD with DVD. Comcast tech was able to fix it by changing the Comcast box diagnostics. Here is what he did. Using the Comcast remote with the TV on - press power, cable, menu in that order. A comcast diagnostic srceen will appear. Select Additional HDMI options, then audio options. Change the audio options to L-PCM. Press power again to exit the diagnostics. That will fix it and you get to use the HDMI cable.
