Hmm...I'm still not sure on a couple points maybe you can clear up. So the image will only look stretched in the anamorphic when the picture is froze while in ifoedit right? The picture will appear normal (though less black bars at the top and bottom of the screen) during regular playback correct? And ifoedit can only be used when the movie is on your HD and not burned to disk right? There is a difference between 16:9 and 2:35:1? Your above post seems to indicate that, but I thought there was only 4:3 and 16:9 and 2:35:1 was just another name for 16:9. Correct me if I read that wrong.

On the disk in question, when I open with PowerDVD and check the configuration tool, the video information shows this information. Is it enough to get the answer? :

Video Attributes:
Video compression mode: MPEG-2
TV system: 525/60 (NTSC)
Aspect Ratio: 16:9
Display Mode: Only Letterbox
Source picture resolution: 720x480 (525/60)
Frame Rate: 30.00
Source picture letterboxed: Not letterboxed
Bitrate: 4.13Mbps

Thank you for your help.
