When creating motion jpg avi the output has no video and will crash Windows explorer.

Using this command:
cl_forceavidemo 1 ; cl_avimotionjpeg 1 ; cl_avidemo 30 ; demo demoname ; video output_filename 30

The output_filename.avi file is very small (about 4MB; I expect around 100MB) and when played with VLC will only play audio.

If motion jpg is turned off the output does have audio and video, although the filesize is nearly 1GB, using this command:
cl_forceavidemo 1 ; cl_avimotionjpeg 0 ; cl_avidemo 30 ; demo demoname ; video output_filename 30

The demo I'm using can be downloaded here:

For reference, in ioQ3 I use this command:
cl_aviFrameRate 30 ; cl_aviMotionJpeg 1 ; cl_aviMotionJpegQuality 100 ; demo demoname ; video output_filename

cl_avimotionjpeg is broken atm. Actually i had totally forgotten about it. I will fix this when I can.

I will probably do somewhat of an cleanup on the avi code as well as it is a mess.

This now works. You can set the quality of the jpeg output with r_screenshotJpegQuality (90 is the default).
