This can happen if a scheduled recording hi-jacks your tuner. If there
are other channels available on another tuner you can still type them
in and switch directly to that channel, they just don't show up in
browse mode. All the channels show up in the EPG however and the ones
you can't currently tuner are marked. (I believe the marking depends on
the theme you are using.)

This ticket http://cvs.mythtv.org/trac/ticket/4501 has a patch for
the browse more, but its approach uses a lot of CPU. We will probably
commit a fix which uses less CPU in the next few months as someone
gets around to implementing something more like what the EPG uses.
