FLV trouble with Flash 8 Player

I was looking at a site that I did with the Flash 8 Player and I noticed that after watching a couple of the FLVs they would lock up the site entirely. Something that worked fine with the Flash 7 Player. If you click on the buttons on the right, you can get to the videos.

It won't only effect the videos, but also any other external .swf that you try to load.

To confuse me even more, this other site that I set up the exact same way seems to be working fine.

Any ideas?

Thanks,
