Hi, the symptom you describe files appearing to be played at speed has 
just surfaced on my phone app for one problem file so not all software 
is tolerant.

Have you looked at your files with AtomicParsley to see if you get the 
message I get "MPEG-4 Unknown profile" on your problem files?  It would 
be good to learn if we have the same problem.  This is no longer a long 
file problem.

What I do not understand is where and why this fault is present.
