Failed Attempt to view MPEG4

I wanted to test my Connect’s video abiity and went to the Internet Archive list of science fiction movies

http://www.archive.org/search.php?query=science%20fiction%20AND%20collection%3Amoviesandfilms

Scrolled to the bottom of the page and “Save link As” to download one of the MPEG4 vesions. It saved as type MPEG4 Audio File. Well. I copied it to the Connect’s Photo & Video Library and ran it.

What I got was a video with no audio with our without phones.

What gives?

There are several existing threads that discuss the supported video formats on the Connect, including this one:

Not all MPEG4s will work, they need to have the proper video and audio attributes.
