An update:
demuxer lavf should work now with MPEG transport streams.
Most PAFF samples (in MPEG ts) play fine with -demuxer lavf -nocorrect-pts, only
premiere-paff.ts (I don't know where it comes from, it shows a German soccer
match) needs -mc 1 (and -nocorrect-pts).

Should we make -nocorrect-pts standard? That would fix most samples with
-demuxer lavf. Or, even better, -nocorrect-pts -mc 1?
