Why is widescreen movie tagged as 4:3 ?

[jntaylor63]

doing a back-up of Armageddon R1 with TMPGenc and found something strange. DVD2AVI and IFOEdit says that the movie is 4:3, but its shot in widescreen (2.35.1)

Why is this?

I don't know that particular version, but it's not something daft like they've formatted the widescreen presentation in a 4:3 frame, ie it's not anamorphic ?

Actually it's because it is a widescreen letterbox format

I've got more info from amazon.com concerning that release:

Widescreen Review:
Picture Quality: 4 (5 is the highest rating)
The dual-layered DVD is not anamorphic, but exhibits good image quality. Images are sharp and detailed with natural color fidelity. Sadly, the DVD was not anamorphically enhanced nor authored using a component master, and digital coding artifacts are apparent as is image enhancement. With all the special effects, the clarity would be dramatically enhanced, but Disney evidently has a policy not to release in the anamorphic widescreen format. The picture is framed at 2.32:1.
