OK, this seems to occur only on films that are in RGB format, and I thought it was the ConvertToYUY2() line that was causing it. But I loaded the original avi file directly into TMPGEnc and it looked fine, I then loaded it via a simple AVS script with NO filters...and there were purple blocks all over the film...I loaded the avi file in VirtualDub and the purpleness was there again, but when I play the film in Windows Media Player its fine!! Help!! I can't think of why this is happening...I tried to load it using DirectShowSource instead of avisource, but TMPGEnc would crash while encoding.......
Annoying as I only recently fixed a more severe "green haze" XviD problem...ah well. Turns out it was in Windows Media Player too, just less noticeable.
