I edited some DV video clips (all 4:3 aspect ratio) using Final Cut Express. I exported them as QuickTime movies and they all show in Finder that they have 720x480 dimensions and they play in QuickTime Player normally (i.e. not squatty). However when I put them in an iDVD project they always come out "squatty", the aspect ratio is being distorted. When I try to preview it iDVD is always comes up as "widescreen preview". Is there any way to force iDVD to use the aspect ratio of the source material or should I use a different program?
