I can make a mov OK but got wrong framerate for avi

Question

Hi,
I modified the jpegtoMovie.java to generate a avi file.
I set up a int[] buffer to store the rgb values and stream it out
to a file. When the format is QuickTime, everything is fine, however
when I changed to AVI format, the windows media player played it really
fast. Windows shows it got a framerate of 1000 and a duration of 0.
I tried to modify the data source to return a duration other then unknown, but it doesn't work.
Any one got any ideas? Attached is the source
Thank you!
