[PD] Using Compare with pix_video

[Ivan Franco]

Hello everyone.
I'm having trouble using pix_compare with a pix_video stream together 
with a pix_image.
I want to do lumakeying but the pix's don't have the same size (the 
videostream is not a power of 2).
So I get the following from Gem:

Gem: GemPixDualObj: two images do not have equal dimensions

Anyway around? Using Windows XP + Gem 0.888-rc2
