According to Lumious Film & Video Wurks the Spanish DVD of Abre Los Ojos/Open Your Eyes is anamorphic http://www.lfvw.com/open_your_eyes.html

I've always thought it was non-anamorphic widescreen...has it been re-pressed? Is their info wrong?

As far as I know, it always was Anamorphic

Mine isn't.

...ahh... my copy of the edición especial coleccionistas ( http://www.veo-veo.com/media/detalle.asp?d=6050&e=0 ) offers a very nice 1.85:1 transfer and DD 5.1 sound ... but it is not anamorphic! (...I have noticed that few Spanish DVDs are...)...

. . . . . .

The R1 version is anamorphic.

I bought a copy from Luminous, and it's not anamorphic. Their description is definitely wrong.

The french edition in the 'Auteurs' series appears to be anamorphic 1.85, DD5.1. See listing here

but ... only french subtitles, no english.
