Not anymore, there use to be 1, 2, and a third key that were available, but Roku update took them away. No IR commands for these commands are recognized anymore:( You were able to unplug the power from the Ultra, its remote switch to IR, and teach your universal remote the 1 & 2 keys, but it doesn't now.

Google is not going to pay Roku for a $1 per button per remote for YTTV, when they have streamer of their own to sell, the chromecast.

Funny thing even though UEI remotes with efc's for Roku no longer have 1, 2, and 3 buttons, there is still an efc for microphone button, of course that's useless without an actual microphone on the UEI remote.
