1. I have Verizon FIOS and selected them as my provider during setup of Live TV but the "Verizon FIOS" automatic selection for the set-top box (STB) didn't work. I had to manually enter "Motorola" (the manufacturer of the FIOS STBs) to get it to power on/off, skip forward/backward, rewind/fast forward, etc.
2. The Live TV Surround Sounds (Beta) feature only works on 1 channel (ABC) for my FIOS STB. When I change channels to other stations (NBC, CBS, etc.) they come across as stereo (left/right) only.
3. I'm running the HDMI out of the XB1 to my Denon AVR-X4000 receiver.
This post is really just to document that my setup isn't working with the Beta surround sound feature in hopes that it will be fixed in a future release.
