Movie Channel, This Channel and Comet Channel are not working.
Are you getting any error messages? Were you able to watch them before?
When you say "The Movie Channel," do you mean TMC (which is a premium channel), or the "Movies!" channel?
Also, can you tell us what your ZIP code is? That way, we can try to figure out just who is broadcasting them in your area.
Note that Movies!, Comet, and This are all carried on "subchannels" of other stations. It's hard to believe that all three would suddenly go off the air, unless you happen to live somewhere where all three are broadcast by the same parent station.
Movie channel, Comet and This is now working. What was happening was that it was so blurry and doing a digital pixal dance on the screen you couldn't even see anything but color. Its all good now.
