[mythtv] Bug: Not recording after conflict with live tv

[Ben Bucksch]

I am using CVS version from Jun 21/22.

I was watching live TV at 20:15 when Stargate was about to start, the 
usual dialog came up, telling me to decide between continuing live tv, 
exiting live tv and watching the recording. I chose to exit. 
Nevertheless, I now see that Stargate didn't get recorded. Andromeda, at 
22:15 immediately following Stargate, did get recorded.

I see nothing relevant in the backend log - in fact, I don't even see an 
"Changing from None to RecordingOnly" entry for Andromeda.
