Regarding Picture Quality: Really?? Where are you located (your comments about "channel unavailable" on TW point to node problems in your neighborhood)?
The thing that most people do not realize is that as soon as that fiber enters the house it is converted into RF video - no different than ordinary cable. The modulation scheme is QAM and the QAM specs are IDENTICAL to that used by TW and other cable systems. From a practical standpoint, the number of HD signals per QAM is independent of the feed to the house (hybrid cable or fiber).
That being said, the decision on how to pack those QAMs is up to the video distribution company (though there are some FCC restrictions on degrading quality of OTA stations). It could well be that Verizon has made the decision to NOT put 3 channels on a QAM (2 HD channels on a QAM fit with no added degradation of signal).
Another issue is that apparently Verizon has been backing off in their support of FiOS (the cell phone business is more attractive).
I'm located in Amherst.
Picture Quality?? Yes really. I talking about compression, not modulation. It appears to me that TW re-encodes the MPEG stream to use a lower bit-rate so that it can cram more video streams into an RF channel. Try watching a football game when there is lots of movement on the screen. Pixelation to me appears far worse on TW versus OTA or FiOS.
I dropped TW about 3 years ago before switching to FiOS. I don''t know about any specific node problems in my neighborhood, but I saw the "channel not available" message often enough on TW. It's a byproduct of SDV. If you don't have the bandwidth to carry all the channels all the time, then I would expect contention for the available bandwidth and therefore "channel unavailable" messages.
I understand the RF aspects of the distribution network.. I agree with you regarding QAM modulation. But there are 2 major RF differences between the TW and FiOS networks. First,TW in Amherst uses channels 2 - ~65 for analog channels. FiOS does not. Second, the optical to RF conversion occurs in my house for FiOS, and somewhere in my town or neighborhood for TW (not sure exactly where). The shorter RF path length allows the use of higher carrier frequencies (more RF channels) and hence more RF bandwidth. When I had TW, the technician at my house had a hard time delivering the higher frequency carriers to my house with an adequate SNR. ( I am literally located at the end of the TW cable in my neighborhood)
Point being, FiOS has more bandwidth, more QAM signals, and therefore can deliver more "equally compressed" HD signals on the coax going to my STB than TW.
With more RF bandwidth FiOS is not under pressure to heavily comperes their signals, so I don't get the pixelation that I saw on TW, and I am able to watch any channel I want without an" unavailable message."
I have not needed to use their support, so I can't comment on that
