If you are using Ubuntu 9.04 and having trouble viewing videos in a website just download flash 10 from Adobe and select .deb for Ubuntu 8.04+ or you can use the tar.gz for linux. I suggest using the .deb for ubuntu 8.04(deb.package installer) save the hassle writing the command in terminal. This problem only happens with a fresh installation but if you are upgrading it from 8.10 it should be no problem.
