Does Tools > Options > Television > Advanced > Show Status reveal anything on the server?
This is the output while the server is quite happily playing a channel:
This lists the status of television devices and recording actions that are queued. The text will also be placed on the clipboard.

I then stopped the channel, loaded up a client and connected to the library and then played a channel from the client. Something different happened this time, I got a fullscreen display view window onteh client with "Opening..." flashing at the bottom for about 10 seconds. I swiutch back to standard view to see if there wer any error messages and I got:
"Something went wrong with playback. Details: Failed to open or parse file. (hr=0x800004005). I Ok'd the dialog and went to the server to get the status.

I tried selecting a channel again and got the same Opening message but let it continue and this time it actually worked. The TV channel appeared on the client.
OK, so...
I closed MC down on the client then rebooted the server and tried again, and again it worked. So I'm sorry, I can't reproduce this tonight! I just couldn't get it working at all last night.
