If you render an AVI with pIllusion 3.0.2, you don't have any problems, right?
Close pIRender.
If you're familiar with Regedit, please run it and look at the following key:
HKEY_CURRENT_USERSoftwarewondertouchpIllusionRenderSettingsAviCompressor
Edit it, and set its value to "0", then close Regedit.
If pIRender still crashes when you click the AVI Options button, delete the whole
HKEY_CURRENT_USERSoftwarewondertouchpIllusionRender key.
Let me know what works.
Alan.
