Unstable Live TV and DVR

I recently installed the Hauppauge WinTV-quadHD, and I have made sure that the Plex server, Android app, and tuner drivers are up-to-date.

Here are just some of my problems:

  • The 4 tuners are split into two 2s – the choice of channels are different on each somehow, even after multiple scans on each pair.
  • Sometimes unable to watch live TV due to the error “Unable to tune channel (timed out)”, yet a recording on that very channel is fine to then be viewed later.
  • Android Plex app has started crashing literally every 10 minutes when accessing the Program Guide since installing the card.
  • Often get yellow triangle with an exclamation mark saying that “There was a transcoder error” when recording something.

Is anyone else getting any of the above issues? Are all/any of these known to Plex developers?
