Video not viewing

Hello,

The problem I am getting is just with one video. A sign is coming up in IE6 saying it is no longer available. However, it stil shows under live. This video works fine for a few days and I only noticed it was no longer showing under IE today. The other video I uploaded however is working without any problems.

The video which is not showing under IE6 is showing under Firefox.

Has anyone had a problem with just one video?

And what would you recommend please.

Hoping you can help.

Regards.
