Exactly, Live TV is a contract between you and MythTV where you steal a 
tuner away from MythTV so you have full control over that tuner.  
Therefore, you can't have Live TV when all your tuners are otherwise 
busy--you have to watch recordings at that point (including the 
recording-in-progress that appears at the top of Watch Recordings).
