Are you able to pass copy guarded material from original retail DVD/BD?
If so your setup is out of the ordinary. It seems that most manufactures restrict the digital audio output to stereo when the original source is copy protected.
I personally ran into this limitation, and found information to be scarce.
However, below is the always reliable copy/past from the all mighty GoogleVIZIO:
"When the DTV [cable/antenna] input is selected for viewing, the digital audio associated with digital programming will be available on this SPDIF Optical connector for connection to your home theater system."
"If your sound system has a SPDIF (optical) digital audio input you can connect it to the optical DIGITAL AUDIO OUT at the rear of [this TV]. This is active when receiving digital audio with the programs from the DTV/TV CABLE/ANTENNA input."
Dolby Digital 5.1 audio is available at the Digital Audio Output only when received as part of a Digital Antenna signal being viewed on the screen.
No audio out on optical when using HDMI.
The DIGITAL AUDIO OUT terminal may not output some digital audio sources because of copy restrictions.
Note: When signals are input from the HDMI terminals, no signals are output from the DIGITAL OUT terminal if they are copy guarded.
[the digital terminal] outputs stereo only from HDMI sources.
Other manufacturers will pass multichannel from the digital audio output, but it is not clear if this pertains to copy protected material.
I have a Pioneer plasma and they seem to have the strictest enforcement. The Pioneer outputs 5.1 if the tuner or analog inputs are the source but there was no audio output from HDMI sources. I ended up getting a new AVR with HDMI input.
I wish I could find an official source, but I haven't yet. So take this for what it is worth.
Java Jack has me sold. I asked the wife for the Zino for Christmas. I wonder if I should start to worry about the demand being too high. I really want to wait to read some more reviews, but I might have to have her order it earlier.
