I'm trying to download the packages, but not working

[dbzmanwoodland2]

I go to software sources and add the link to download boxee for ubuntu 8.04 hardy. I get this error message when it tries to download it

deb http://apt.boxee.tv hardy main is what I'm using as the link

Failed to fetch http://apt.boxee.tv/dists/hardy/main...64/Packages.gz 404 Not Found
Some index files failed to download, they have been ignored, or old ones used instead.

Do I need to do something extra to make the download work?

There are no 64bit packages for Boxee, yet.
