Check your playback profile. You should have "Openmax normal" selected.
Also edit the profile and check that the decoder and renderer are both
set to openmax. Set the number of processors to 4.

Do you have the latest version? There was a bug with dropping frames
that has been fixed. "Unknown decoding error" is one message that
occurred with that bug.

What type of content is this? Is it MPEG2 or H264? Is it recordings or
videos? Is it only one particular recording?

Are you using an on screen display (e.g. Subtitles or Info)?

If you still have problems let us know your version (mythfrontend
--version).
