The list of media servers on Wikipedia is a bit overwhelming and I've had experience with firefly not being well maintained with regards to keeping up with newer standards. My specific need is being able to access media content from laptops (Windows 7 and Linux) and a Samsung TV with DLNA. I've considered MediaTomb, but since I haven't yet bought the TV I want, I would like to choose media server software which would work when I get the TV (considering Samsung LE40C755). MediaTomb hasn't had a release for over a year, but not sure if this is a problem. Support for PS3 would be OK, but no show stopper.
Any feedback from people with experience setting up media server with similar requirements would be appreciated.
