I think this post belongs here rather than in the PVR group. Using TVHeadend (4.2) I recorded an episode of Doc Martin with stream profile of "pass". Playing it back lip sync was out and it was "stuttering" sort of freeze of a 10th of a second to give jerky movements.
I copied the .ts file to a memory stick, plugged it into one of the TVs USB ports and playback was perfect. I've recorded 3 other programs to test (different times, different channels) with the same result.
Recordings are being saved onto the SSD that Kodi runs from so to eliminate that I copied the .ts file onto the 6TB HDD I store my films on. Still stuttering on playback.
I'm guessing the issue is caused by ffmpeg so I'm going to try changing the stream profile to "matroska" and see if that helps. I'll report on that later today.
