you really haven't looked a bit further than the software have you?
The things you need are the following things: UPnP (universal plug and play) and DLNA (digital living network alliance).
We have 2 UPnP servers on the ipkg repository: ushare and mediatomb
ushare is simple to set up, but not very good when it comes to compatibility...
mediatomb has better compatibility, but it's quite slow imho.
Also a comercial server is available called Twonky Server.
I use twonky, simply because it's the best in the market and because they are member of DLNA.
Obviously I'm not telling you to go buy stuff, that would be bad thing. Instead, try out the opensource servers available to see if they're sufficient for you.
If not you can try twonky (30 day trial).
