Movies Recorded Through the NetLogo `movie-start` Primitive Don't Play Properly #24

If you record a video in NetLogo using movie-start, you can play it back in QuickTime just fine. However, if you try to open it in the video extension, it will not play. _But_ if you try to open it from the GStreamer command line, even their 'qtmuxer' can't decode the thing. Furthermore, VLC Media Player chokes on it (despite doing fine with other '.mov's), saying:

"No suitable decoder module VLC does not support the audio or video format 'twos'. Unfortunately there is no way for you to fix this"

With this being the relevant part of the crash log:

araw error: bad channels count (1-8): 0
main debug: no decoder module matching "any" could be loaded
main debug: TIMER module_need() : 17.400 ms - Total 17.400 ms / 1 intvls (Avg 17.400 ms)
main error: no suitable decoder module for fourcc `twos'. VLC probably does not support this sound or video format.

As such, I don't see this as a bug with the extension; it's a bug in NetLogo, from what I can tell. I can't reasonably fix it on the extension's end.

It's a known issue with JMF that it generates mov files that a lot of tools can't read. So yeah, not a bug in this extension.
