I swapped out my greenie for a new bluee Motorola in Ann Arbor, MI at the beginning of September 2015. I did this by calling Xfinity customer service and complaining that my dvr was defective. They wanted to send a self install kit, but I insisted on a service person to install it. They said that would be an extra $50 for the service call. I countered with a request that they waive the service call fee. They agreed, and when the service guy came, he had new blue boxes on the truck.
Even when using the HDMI detective to present the greenie with 5.1 capable signals, when dealing with "stereo" programming, the greenie would only provide front left and front right to my surround sound Onkyo, whereas the bluee provides left front CENTER and right front, which is a considerable improvement. In addition, I was having problems with the greenie DVR writing bad blocks that would jump back to the beginning of programs. In addition the greenie had some display artifacts in the program guide. All of these problems were fixed with the bluee.

This is an update to my previous post where I described using a GEFEN EXT-HD-EDIDPN HDMI Detective Plus to "fool" my X1 greenie into thinking that the TV had surround. Because I was experiencing erratic behavior with recordings spontaneously jumping back to the start, and some display artifacts, I exchanged my greenie for a new Arris blue. With the same version of firmware (1.55.02) the greenie showed none of the recording and display issues. More important for audio, the Arris MX011AN_2.1 correctly feeds my TV left center and right channels for non-surround programs, and surround when available. The greenie did not provide a center channel for stereo programming. Overall, the upgrade from greenie to Arris blue was worth the effort for me. The arris blue still cannot be override set to surround without a GEFEN Detective Plus or equivalent. I encourage Comcast to re-think this feature and provide a three way choice of [Auto, stereo, surround]. If you choose stereo or surround, it should stick and give it to you.

A Success Story (sort of) fixing #1Surround Sound After more than 2 years of blah blah, I have surround sound, and it is good, though still not perfect. My Hardware Configuration: Pace DVR (greenie): PX001ANM_2.02p12s1 Running xappl-XRE.55P5 Server: 1.55.05 7/30/2015 using HDMI out => HDMI in => GEFEN EXT-HD-EDIDPN HDMI Detective Plus (~$120 Amazon) HDMI Detective Plus is an in-line HDMI device that can capture and spoof EDIDs. HDMI out => HDMI in => LG-55lw5600ua TV – Audio TOSLink optical out +> TOSLink in => Onkyo HT-R560 AV Receiver (7+1) Note: 3 years ago, I had a Motorola DCH3416 STB connected via HDMI to the same TV connected to the same Onkyo receiver via TOSLink and the surround worked flawlessly. Experimental Method: Using the Gefen Syner-G software (PC to USB to Detective Plus) I captured the EDID of the LG-TV, then configured Detective Plus to show a variety of modified EDIDs to the Pace STB, noting the type of input received by the Onkyo.. Experimental Data: HDMI Detective Plus, reported that the EDID of my LG TV showed only one SAD (Short Audio Descriptor) which was “Linear PCM 2 channel” with two speakers. The LG-55lw5600ua has two built in speakers. Key to Abbreviations: Linear PCM 2 channel (stereo) 48khz = LPCM2 Linear PCM 8 channel = LPCM8 Dolby Digital 5+1 (Surround) = AC3 Dolby Digital+=DD+ Surround protocol, but only Front L+R channels have signal = SurroundLR Cannot save Surround Sound setting on X1 menu= X1NoSS -------------------------------------------------------------------- Source + TV EDIDs + Receiver In + Speaker Out| Box Setting | ---------|-------------|-------------------------------------------- Stereo | LPCM2 | LPCM2 | Stereo | X1NoSS Surround | LPCM2 | LPCM2 | Stereo | X1NoSS Stereo | LPCM2 + AC3 | LPCM2 | Stereo | X1NoSS Surround | LPCM2 + AC3 | LPCM2 | Stereo | X1NoSS Stereo | AC3 | AC3 | SurroundLR |Surround Surround | AC3 | Surround | Surround |Surround There are many other data points which can be summarized as “all EDIDs except AC3 and LPCM2 are ignored by X1”. Analysis: I am currently running withHDMI Detective presenting only an AC3 EDID. When the program source has surround, I get surround, and when it does not, I get front left and right (but not center) from the speakers. The failure to recognize AC3 when the AC3 EDID audio descriptor is paired with LPCM2 SAD means that with my current firmware any device that advertises that it will accept LPCM2 is stuck in stereo regardless of additional advertised capabilities. Since the firmware appears to ignore any audio EDID other than LPCM2 and AC3, devices that represent themselves as a higher level such as LPCM8 channel or Dolby Digital + 8 channel will default to LPCM2 stereo output. Conclusions: The Gefen HDMI Detective Plus is a useful gadget that has given me a look into the facts of my situation. Since my X1 box steadfastly refuses to output AC3 whenever it detects ANY LPCM2 in the EDID I remain short of my ultimate goal of being able to have my Onkyo provide true surround when available and to auto sensing and expand LPCM2 stereo to pseudo surround via Dolby PLIIx. The receiver could do this trick if the X1 box switched from LPCM2 to AC3 depending on program source as has been suggested in other postings. Given the speed and accuracy with which this self inflicted problem has been addressed, I am not optimistic. For those that really want surround now, the Gefen can do it for ~$120. The device requires power to program it, but operates from HDMI power in normal operation, and will present the EDID that you want even if the TV (or receiver) is powered off. The device does what I needed. I should mention that I tried the similar ConnectPro device (half the price), but it was programmable only by dipswitch, and did not provide the capability required to fool the X1.
