I'm sort of with Karyudo on this bit, there's no point in doing the calculations to n-th degree accuracy if the tolerance the display device can be up to 5% out.

Plus the fact that many people will find this useful for converting downloaded AVIs into DVD, and many AVIs have aspect ratios that are slightly off to begin with to comply with the mod-16 size requirement.
However I think it would be nice to have a checkbox to say "correct values for CCIR compliancy" so that users have the option to use it or not.
