Since I did not really understand the paragraph I cut:
Do you mean that although you used -probesize and
-analyzeduration, the time to probe a file did not
If yes, this sounds like a serious bug that should be
(Needs command line, console output etc.)

I may miss something but I wonder how you want to
demux a transport stream without some probing /
there are many tickets from people who miss their
subtitle streams when opening their file...
Additionally, user streams without PAT and/or PMT
are not unusual (there used to be a bug in *zap
for many years), so careful probing in transport
streams is particularly important afaict.
