Any particular channel you're watching when this happens? Roku can pass your key presses on to the channel app, but what the app does with them is up to the channel's app developers.
Edited to add:
More and more apps are abandoning Roku's default * key for accessing options in favor of their own key selections. I think this is to maintain compatibility with their apps on other platforms.
See if pressing the up or down direction key brings up the channel's on-screen options, as this is used by a number of channels.
