I just saw this over on AVS Forum -- the first h.264 Fios channels have rolled out, on 1472, 1473 and 1474. These are part of the baseball package, and I'm not subscribed, but I can confirm that my Premiere shows them as h.264 in the diagnostics screen. Someone who subscribes to the MLB package should check them out. May require 20.2.0a. But I'm putting this in the Coffee House instead of the Premiere section in the probably-vain hope that even a Series 3 might pick them up.
