Thanks for the contribution, but the link cited is not going to provide any insights into this matter of why Premiere Elements 13's Interpret Footage and Properties readings for mod widescreen are different for the same sample in other Premiere Elements versions on the same computer.
As mentioned earlier, all indications are that there is a flaw in this already delicate interaction between Premiere Elements (any version) and .mod widescreen import.
Just added to the observations...same results even if mod widescreen 16:9's file extension was renamed from .mod to .mpeg prior to import into Premiere Elements.
August 24, 2015 Update On The Matter Of Premiere Elements 13 Major .MOD Widescreen Concerns
The following is an excerpt from my Premiere Elements 13 Daily Discovery Blot which suggests a way to use these .mod widescreen files in Premiere Elements 13/13.1
Item 13 in
Update...a possible workaround seems to be
a. Set the project preset manually to NTSC DV Widescreen or PAL DV Widescreen
b. Go to Expert workspace Edit Menu/Preferences/General and remove the check mark next to the preference "Default Scale to Frame Size".
c. Import the .mod widescreen into the project with the project's Add Media/Files and Folders/Project Assets, and drag the .mod widescreen from Project Assets to the Timeline Video Track 1/Audio Track 1.
d. Click on the Edit area monitor to bring up the image's bounding box with handles. Click and drag on one of the image's bounding box handles to scale the image to the point where it just fits the space provided in the Edit area monitor by the project preset choice
