DRM and a new computer

[chefws]

I got a new computer
I am wary of using any drm mp3 players. I think all of the preloaded players have drm, cuz they are all the latest releases. I have a copy of MusicMatch 7.1 that doesn't have the DRM software, although they tried to fool me into upgrading.
What can I do to keep my files my files? I am going to use the new comp as a media server, and need a cross-network player/server.
I was wondering if anyone has any input on how to do this effectively without having to use any Microsoft Product, or anything that would cause DRM problems.
I found these proggies, but haven't used them.

btw, the new comp comes with tv card, dual layer dvd burner, 150 gig hdd, radio, all the extras

Any help would be appreciated.
Thanks
