Interesting... what are you using for mouse and scrolling? I tried it several months ago and could not select channels either with the voice remote or k400 keyboard/mouse. Also are you using this app from the Google Play store:

I see it was updated 15 April which is newer than the version I tried.
Weird... This looks just like the Spectrum TV app on the play store.........
if you'd do me a favor. can you confirm you can install spectrum tv on it? https://play.google.com/store/apps/details?id=com.TWCableTV
