Switching live tv-channels sometimes causes subs not to show up. From my short test, live tv subtitle never fails if i start a channel from stop, only when zapping it fails (and not all the time)
Tested on rpi and Osx

1, zapping some channels
2, zap on Discovery world- no subtitle
3, stop live tv playback and direct play Discovery world- subtitle works fine

Tvheadend as backend.

Never seen this issue in Frodo
