I've noticed this only on a few videos posted by a fellow named Dj0287. I am all but positive this has something to do with the way the video was encoded, and nothing (or little) to do with YouTube.
but that doesn't explain why the videos were normal sometime in the past, and suddenly are squished.
though i'm not an expert at it, so how knows.
i was just asking is if it can be fixed, cause its annoying the heck outta me. lol.
there are definitely more videos i've seen squished, i thought it was a problem on my headend, but now i'm kinda glad it's not.
