Tested on Linux, from this point in tree search for mp4 or mkv or avi and spit some of the mediainfo
Code:
find . \( -name *.mkv -o -name *.avi -o -name *.mp4 \) -exec mediainfo {} \+ | grep -E 'Complete name|Format/Info|Width|Height'
(would need some work I guess)
p.s. And yes you should really fix this html code box width already.
