Well, it's a tad late now. Years ago when they were raising my rates while degrading my quality they told me over the phone that I am lying and video quality is much better now that it is HD and perhaps I don't know what I'm talking about and watching SD.
Glad to hear they've finally admitted its an issue that needs to be addressed, though, and, possibly addressed it. My neighbor though still has really shit video quality on Comcast compared to OTA, even as late as last month when he commented how vastly different my PBS feed looked. He asked if I had some sort of 4k feed or something (right!). I went down to his apartment and saw what he was watching and yeah, still night-and-day difference. Perhaps they haven't rolled out switched digital video to my area yet.
