I do believe that this will be negative only if SMPTE is set for that file
(&H54).

But, what if it's in the header? Two bytes for the division. If the first
one is negative (last bit set) it's using frames and subframes, else just
the regular PPQN. I can't just ignore that can I? I must say I haven't
seen
a MIDI file using that, but it's in the header description... They just
don't explain it to well...

This is for SMPTE synchonisation.
Frames are 1 second...subframes are the number of events per
second. Mostly
used to control video instrumentation (subframes 24 subframes per second
for
example).
as far as MIDI is concerned you don't need to be concerned with these
values.
