I have never heard of a TV or a set top box that outputs a 3 channel signal. Or does mono, for that matter.

Just because i am curious... What are the audio output settings of the Cisco box and the LG TV where you cannot get sound from the surround speakers? And, what is format of the source audio on the Cisco box - DD 5.1 or stereo PCM?
The Cisco has Dolby Digital, HDMI, and Other as output choices. The LG TV has Auto and PCM as output choices. I normally use Dolby Digital (Cisco) and Auto (TV), but have tried all possible combinations previously. Of course, with my current working setup between the CISCO, OREI converter, and Bose, the TV audio out is out of the loop anyway.

The current setup works equally well with the CISCO set to Dolby Digital or HDMI (for some reason). Selecting Other on the CISCO drops the rear surround speakers, so it's back to my original issue.

As far as source audio on the CISCO, I see no control for that, so I "assume" it is whatever the broadcaster chooses to send down the coax to my CISCO box (often DD5.1 I'm guessing).

Thanks for your interest.

That's an odd set of choices. Dolby Digital is a set of audio codecs while HDMI is a transmission medium. But, of course, when using the analog stereo outputs, neither Dolby nor HDMI should be a valid selection as they both refer to digital, not analog.

The TV appears to have an information bar. Does that give any information about the type of audio it is receiving from the Cisco?

Now, that's odd. I wonder what Other does.

Yes, it's the station. Most HD channels have DD 5.1 while SD ones use stereo. Is there any difference in performance when you switch between HD and SD stations?

Also, do you have a another device such as a DVD player that you can try in place of the Cisco box to see whether it has the same limitations when using the analog stereo outputs to your Bose?

The selections dont change ever on the Cisco. I originally used the analog stereo outs on the Cisco directly to the BOSE, and no surround to the rears. I have no analog outs on the LG TV, so that was my only option a couple weeks ago. Now I'm using the digital optical out on the Cisco, to the OREI converter, then to the Bose - just to reiterate.

No. Occasionally I'll see on the TV that a particular show is in DD5.1, but that's at the broadcaster's discretion.

Now, that's odd. I wonder what Other does.

I have no clue. Thought it might be PCM, but if so why not just say PCM?

Yes, it's the station. Most HD channels have DD 5.1 while SD ones use stereo. Is there any difference in performance when you switch between HD and SD stations?

No.

Not at this time. Back in the day, I had a VCR and a phonograph (yes I'm old) hooked up to the TAPE and AUX inputs on the Bose - worked perfectly with full rear surround. But I had to select full surround on the BOSE remote for those two inputs, which default to stereo. The VIDEO input on the BOSE is the only input that defaults to full surround.
See above for answers. Clearly I didnt quote and answer correctly.

It's an oddity. Not sure what's going on with the analog output of the Cisco box. But, you have a solution. And that's all that matters.
