jit.qt.movie return incorrect time

I'm playing a movie using jit.qt.movie and the time it reports is going at about half the speed it needs to be.

So if I start the jit.qt.movie file playing, and a few seconds later start the same movie file in a quick time window . . . the quicktime window time catches up the jt.qt.movie and surpasses it, eventually reading double the time of jt.qt.movie . . .

any ideas why this could be?

I also had a metro timer that was seemingly doing the same thing, ie not banging at the right interval.
