Maybe it's some kind of header in the midi file?

Are you using cat or playmidi to play the file?  The cat method will dump the 
data to the midi port, but it could be in the wrong format.  

A really handy way to find out what sysex data is in a midifile are the 
utilities mf2t and t2mf, which convert midi files into human-readable text 
files and vice verssa.  I believe they are included in the latest version of 
scala from http://www.xs4all.nl/~huygensf/scala/downloads.html
