I think this is mainly due to frame numbers (e.g. desiredFrame) being
0-based and framesPlayed, effectively, being 1-based.  For example,
when DoFastForward says go to desiredFrame=1000, it implies showing
the frame when framesPlayed == 1001.  I know I was confused by this
when working on the ivtvdecoder.  It makes it easy to have an
off-by-one error.  Or should that be an off-by-gop error?
