If your in to video/music streaming to your devices definitely give Plex a try, I decided to try it because I came across it looking for a replacement to PS3 media server and it works with Linux, so I installed Plex with no problem had to forward a port and change some permissions (I think) but I'm loving it.
Organized all my movies and music, added cover art and even provides movie descriptions, I have yet to test it in depth on the PS3 but as far as I have it looks very promising, more responsive than the PS3MS, I have yet to watch a full movie but the part I did was quite smooth.
I think a windows install would probably go easier you might need to know a little about firewall exceptions and maybe run as administrator, I'm not sure have yet to install it on a Windows machine.
Here is a couple screen shots and a link to
