Chris, I believe you are mistaken
Authored by: RideMan on Jan 19, '06 08:51:52PM

I think you're right. 8-)

ALL DV movies are 720x480, regardless of whether they are 4:3 or 16:9. Apple does something in iMovie HD and possibly in some versions of Final Cut to identify the reference movies to iDVD as wide-screen. Those of us who don't use iMovie are stuck, unable to get iDVD to identify our widescreen movies as widescreen. The script that Chris linked to corrects that problem, somehow causing iDVD to correctly identify the movie as widescreen. I think it's the 'wide' atom in the movie udta atom, but I haven't tested that hypothesis.

Anyway, once the movie has been run through that script, iDVD will correctly encode it as a widescreen movie. That's a good start, but when iDVD creates the movie control file, it sets one bit in an unexpected manner. I don't want to say it's "wrong" because it is a legal setting ("pan and scan prohibited; letterboxing prohibited") but it is not the expected setting ("letterbox on 4:3 set"). THAT is the change that the Perl script makes.

You only need the anamorphiciser fix if you're not using iMovie HD. The Perl script affects anyone creating widescreen content and using 4:3 TV sets.

Thanks for the plug, by the way. My apologies for not submitting it to macosxhints.com myself!
