[RS] Conflict message.

Conflicts have been detected in your recording schedule on the HDR-Fox T2 (humax - dc:d3:21:57:91:39)
The following events conflict:

104 Channel 4 HD Sat 13/05/17 21:00 - 23:35: 12 Years a Slave
(2013) Oscar-winning drama about slavery in 19th-century America. Star
102 BBC TWO HD Sat 13/05/17 20:30 - 22:10: Woman in Gold
The reason I am getting this message is that I've set a reminder for 101 BBC ONE HD Sat 13/05/17 20:00-23:25.

As these are all on the same MUX, is this conflict warning valid?

Or will one of the recordings fail?
