[mythtv-users] Pi3 Playback problems with 1080i MPEG2?

[Tom Harris]

I just set up a new Pi3 frontend on Raspbian Lenny + Peter’s .deb package
for 0.27.
After some tweaking of various settings in raspbian and mythfrontend, it is
working well.

The one issue is that playback of 1080i content has problems.  It misses
frames, pauses, and is generally not watchable.  720p video is fine.

I verified a few things in debugging it:  content streams are fine,
bandwidth to frontend is fine, settings are correct (as far as I can tell).
  I played back the same videos just fine via Kodi’s mythtv add-on on my
Pi2 as well as the Apple TV mythfrontend.

‘-v playback’ confirms openmax is enabled.   But, there is an error, which
I’m not sure if it’s normal or a real problem: “E  AFD: Unknown decoding
error"

Has anyone else run into this?   Any more settings I should check?
