A little more information would be useful if thats ok. Have you installed the flash plugins? If not then see https://answers.launchpad.net/ubuntu/+source/firefox-3.0/+question/50208 -- that might help.
If you have then this is a genuine bug, I can play videos fine, so I don't think it is, but its possible.
