I'm trying out a 3gp movie (H.263 codec) in jit.qt.movie, and i can't get an image from it.

Trying it in the qt.movie help file, it reports a time, duration, timescale, fps, framecount, etc. It seems to be ok, except it only outputs black. I sent it through a jit.unpack, and it has a white alpha channel, so it's not a weird mask issue. The movie plays fine in Quicktime Player. 

Is there a reason this attached movie won't convert into a viewable jitter matrix??
