Media Player Playback of mov fails

I'm uploading mov files selected with the uiimagepickercontroller to my amazon s3 bucket but when I then try to play them with the media player framework, I'm told it's an invalid for开发者_运维技巧mat.

Here's one: http://s3.amazonaws.com/irovr/users/9/92f7acd7-31b5-437c-8a30-16630e869d29/DEEDBFAE-8D41-4B52-B223-AA03B3A25491.mov

Solved. For anyone out there that's curious, don't gzip mov files when uploading to S3. Images can be gzipped fine, but not mov.
