Please try the sample again;-)

For me, it shows bad A/V sync issues: Not "bad" in the sense that desync is
increasing all the time, bat "bad" in the sense that video freezes and then
speeds up again occasionally (watch closely when the text "Jakob Antkjaer"
appears if you don't see it immediately).

vlc plays the sample fine / much better...

I reproduced the issue with -demuxer mpegts, -demuxer lavf (you have to
uncomment the line containing "LATM syntax" in libavformat/mpegts.c) and with
(and without) reverting r31349 (default_max_pts_correction=1).

Since my computer is fast enough for this clip, I don't think this is
performance issue.
