The current definition I have here for MOCO channels is as I said earlier @benwiddowson - AMC, BT Sport 1-3, ESPN, Box Nation, BT Sport Extra 1-6.
It's possible the Now Entertainment channels will be available in the Now TV app, but I wouldn't expect them to work from the TV Guide.
Edit: just occurred to me that I'm looking at the channel list for the TV app, so it may not include Now TV channels that aren't available in the BT app anyway. I'm not entirely sure what is currently included in MOCO so I'd say to trust whatever the BT web site offers you.
