I noticed that in the first example with choppy playback, the frame rate is Frame rate : 2.083 fps

Changing the stream profile to 'pass' works okay. It seems to be something when using profile 'matroska'

Could you try to change '#if 1' to '#if 0' in src/plumbing/tsfix.c ?

First try, I got the following two errors:
src/plumbing/tsfix.c:383:9: error: ‘total’ undeclared (first use in this function)
src/plumbing/tsfix.c:384:17: error: ‘srch’ undeclared (first use in this function)

So I uncommented out these two lines:
// th_pktref_t *srch;
// int total;

Rebuilt and it seems to work! Great.

What has that bit of code been excluded from the builds?

If your stream is on SAT, could you give me hints where I can test this (position / channel name)? Or could you give me log for '--trace parser,tsfix,globalheaders' when you tune to the affected channel ? https://tvheadend.org/projects/tvheadend/wiki/Traces
