Here is my situation the other night.
1. recording Nick
2. recording Cartoon Network
I could not tune to my RSN to watch the Hawks. When I would try, it would take me to the screen showing what the tuners/streams were doing. So what did I need to do to change the channel again?
Two ways this happens:
1. Was it during primetime and PTAT was enabled to record those primetime channels? IF so, then that 3rd tuner is in use recording the LiLs so all of your tuners are recording.
2. Do you have a Joey? If any Joey is linked to that Hopper and turned on and tuned to one of the LiLs, then you would have to turn off such Joeys before the Hopper can completely release that LiL tuner.
