need help with video files ripped from xbox 360 game disc

[Clutchins]

i had the brilliant idea to rip the bonus features from the Halo 3 Limited Edition disc, which if you didnt know is an actual 360 disc that wont play in regular DVD drives.

i managed to decode all the files to play in MPC-HC but the display aspect ratio information in the header is preventing the video to display in 16:9. instead it displays in an oddball (heh) ratio of 800:657 and i cant figure out how to fix it without changing my video player ratio settings.

if anybody would like the original files to replicate this issue seeing as this is a pretty niche scenario, im happy to provide.

here is the file: https://we.tl/t-khRZHTb7Q5

here is the mediainfo for the decoded file:

(this disc stores these videos in chunks not unlike a blu-ray, so for example the main documentary "anatomy of a game" is stored in 128 unique 30-sec .m2v files)
