jARToolKit

I was experimenting with JARVideoTester, using video.h by Thomas Pintaric as a reference point for the different config strings to pass into JARVideo's create method. One string that I tried was along the lines of
"inputDevice=AVI_FILE,fileName=video.avi,loopAVI,renderSec"

The video played fine, but didn't loop, despite passing in the "loopAVI" parameter. Is anyone familiar with this problem and is there anything that can be done about it?
