[mythtv] Ticket #2335: LiveTV hangs when a recording is finished and a new on starts (no channel change)

I think so, but you can know for sure by looking in the frontend log.
If there are signs of a player reset occurring then the switch was
discont. Should see FileChangedCallback for continous.

eg. It's discont if you see this type of stuff with -v playback

VideoOutputXv: ClearAfterSeek()
VideoOutputXv: DiscardFrames(0)
VideoBuffers::DiscardFrames(0): AAAAAAAAAAAUUUUUUUUUUUuuAAAAAAA
VideoBuffers::DiscardFrames(0): AAAAAAAAAAAAAAAAAAAAAAaaAAAAAAA -- done
VideoOutputXv: DiscardFrames() 3: AAAAAAAAAAAAAAAAAAAAAAaaAAAAAAA -- done()

The discont'ness can be overridden later on, so the backend log is not
reliable for that.

Yeah, same here. Unfortunately it's beyond me to do much more useful
debugging on the continuous transitions. Hmm, I wonder if they have
ever been highly reliable?
