What specific Roku model do you have? What channels are their shortcut buttons set to? Have you tried reconfiguring the buttons to your wanted channels or different channels for troubleshooting purposes?
Re: [OS 10.5] Roku Ultra shortcut buttons not working?
@Cookease, try pairing your remote again. Press and hold the little button in the battery compartment until the green light starts to flash and then unplug the power from your Ultra for a few seconds and plug it back in. Give it time to restart and find the remote. You may want to put in a new set of batteries or even try a new set before you try to pair it again.
