This is likely bug 1479203. Microsoft are no longer supporting Windows 7 and have not updated their decoders to handle various videos. The video in comment 0 plays on Windows 10, but on Windows 7 the decoders don't seem to handle the high profile involved.

Please name all seven. Then we could check how they work around these issues or if they are the same browser engine.
