videos play fine with Explorer. Everyone get msg "corrupted file" using Firefox. It has to work for EVERYONE who comes to the site, not just me! the site is www.williamthomassleepcenter.com and has considerable number of hits every month. Choose "VIDEOS" from the main page and try to play any of the 7 videos there. It gives everyone the message that the file can't be played because it is corrupt. Of course, no problem when using Internet Explorer.

Please help! Thanks... --Roy Roberts Web designer

"Hits" can be misleading. Some can be others who the video failed as well.

Firefox's web console displays:

"Media resource http://sleep.azmine.com/Videos/I'm%20Comfortable.mp4 could not be decoded."

So "corrupted" is just a guess. Anyway, I'm not enough of a video guru to know what the issue might be.

VLC reports this codec for the video:

Codec: MPEG-4 Video (mp4v)

Try to recode the videos and use H.264.

To display a video using HTML5, which works in the newest versions of all major browsers, you can serve your video in both WebM format and MPEG H.264 AAC format, using the element like this

I can see the video with VLC on Linux if I disable MP4 support for the HTML5 media player.
