I agree, it's been hit and miss way more than it was in the past. I have no idea what is going on. It seems every few weeks, new server. Then, every 2 to 3 days, channels buffer, can't watch anything even when I switch channel, it plays fine for 3 minutes, then buffers for 5 seconds, then plays, then buffers.
As always, it will daily still do the repeat play, where it repeat play a 10 second segment from a channel multiple times. I only use the premium channels by the way, none of the channels with commercials.
It's making me consider just going back to C-band, where you can actually still Al La Carte buy premiums like HBO, Showtime, etc.. These really are the only channels I need, since the broadcast ones are free on Antenna.
