(Footnote: If the "just render 1:1" theory holds, then don't forget sms's comment that the frame size needs to be a multiple of 16 for MPEG encodding--- i.e. 1360x768.) (-matt m.) --- This SF.net email is sponsored by

I think I've figured it out, but if someone could verify my results, that would be great. I think I need to design at 1365x768. Using the information from the VCD stills page and other pages I found, I built a little aspect ratio converter that, given the number of pixels high and wide the destin
