I suggested, and it has been brought to Verizon's attention is regards to the PCM, LPCM, and AC-3. And the Cisco not having the user adjustable hidden settings. They should be adjustable in the Settings under Audio, Auto, AC3, LPCM. Since they are not adjustable in a hidden menu with Cisco. But I believe the issues in HDMI is based on LPCM. I am not sure if this was posted as an idea for the Cisco hardware. But it is known that there is a hidden diagnostic menu on the Cisco, but no hidden user settings, such as found with the Motorola.
Interesting Info regarding AC3 and Dolby digital. Now it looks as if the conflict stands with the HDMI standard being LPCM, and some media standard being Dolby. How is the STB or TV supposed to handle that. I have heard some have used a fiber cable to resolve the issue.
Interesting info RE: Dolby AC3 and HDMI conflict. Handshake issues.
