Video Upload

I have been trying to upload a short video clip to my webpage but have been unsuccessful. I've added a new "item type" that would fit this type of file but that did not resolve my issue. I'm able to input the necessary information, however, when I go to add the item, the website says "connecting" for about 5 minutes and then wipes out all of the information I put in.

Has anyone ever had this problem before? I am using version 1.3.2, I feel that this may be an issue because of the version type but have yet to upgrade.

Many thanks.
