I've tried 2.1.2 and 9999 (latest from git).

I've tried with and without dynamic range compression and the internal
upmixer.  No other options there.

Previously, I didn't usually play videos on this system so it may have
been happening for a while.  It wasn't happening about a year or so
ago.  I've tried a52dec-0.7.4-r6 and 0.7.4-r7.

I just noticed that every time it stutters I get this in the console:

core input error: ES_OUT_SET_(GROUP_)PCR  is called too late
(pts_delay increased to 300 ms)
core input error: ES_OUT_RESET_PCR called
