Please specify Cr-* of the system to which this bug/feature applies (add
the label below).


Steps To Reproduce:
(1) open asos.com
(2) navigate to any item that has a "catwalk" video (some items in the store only have photos, but most have a video)
(3) there is an "oops, error" instead of the video
(4) you can find the actual MP4 in the inspector, but pasting it in the URL bar just gives a white screen, e.g. http://video.asos-media.com/products/ASOS/_media_/76a/76a928f8-cbc4-4b5f-acbb-dd27c42686e2.mp4 - The same video works on Chrome on desktop.

Expected Result: video plays

Actual Result: video doesn't play

How frequently does this problem reproduce? (Always, sometimes, hard to

it?
