Sure thing, although the key word is "supposedly". The post in question suggests using the 3ivx 4.5.1 Mac OS 9 extensions and codec to make the videos at the higher resolution, although i'd be curious to see if it really is 640x480 or just scaled up 320x240, though he seems to suggest the quality of the video the Wings card is handling is pretty top notch.

The file name is 3ivx_d4_451_os9.sit and I downloaded it from Macintosh Garden.

I still have yet to determine if this even works, and if so, how to use it. Feel free to take a look though.
