That may very well be; would you mind sending me that short recording
you have?  In addition, what rev of trunk are you using?  (I don't run
trunk myself, but will poke around other changed files to see what I
can find).  Each filetype probe results in a "score" that is then
compared to others, so it's entirely possible that while what I
applied prevents over-scoring mpeg2 in some cases, other probes that I
don't use need to also be fixed to lower their scores to allow mpeg2
to still "win" in other cases.

Note that the original issue I was fixing wasn't the remote delay; I
was having problems playing h.264 mp4 and HDHomerun mpeg "ts" files
(which this patch addressed for me); it just turned out that this
scoring problem also resulted in continuous reprobing during playback,
which seemed to be the culprit for the delays (and I haven't had
remote delays in the months since I patched it).

Thanks,

Josh
