I need help please

I have a problem when I upload a video to my site it uploads fine, and then says video converting. Then in about 2-5 minutes it appears and plays just fine. But that is only on videos that are 50 minutes or less any video that is 1 hr or more it uploads fine and then says video converting on the site but it never shows the movie it always says video converting. You can see at my site www.myhotbigtgf.com no worries no spam or anything. And my php.ini is extremely large so and I just don't know where to go from here. Here is my source code where I think the problem is anyhow.
