My HR21-100 has gotten extremely slow to respond to remote commands. Been like that since Saturday. Probably going to have to reboot soon. I've not seen it this slow in a loooong time.
Rebooting didn't help mine. Since the update, most of my DVRs have an unbearable lag between button presses and a response by the receiver. Then sometimes, it will have actually received all the commands and will execute them all 5 or 10 seconds later in rapid fire.
I'm also in the "CC is much worse" camp. This is a frequent use item that just got far more cumbersome. 7 buttons to turn on (would have been 6, but they placed the unneeded "DirecTV subtitles" ahead of CC) and 5 buttons to turn off. Adding in the intermittent reception of the remote signal makes it an ordeal.
CC has been around for over 20 years. We don't need a reminder that it is an available feature, we just need to be able to quickly activate and deactivate it. Personally, I'd rather the Format button be a dedicated CC toggle.
