So far, I've moved to PS3 Media server, as well as an app that can access upnp servers for the phone and also PUSH content to other players. For my phone, I use dice player, with a special codec for 'protected' audio.\
All in all, to use my pc with my samsung tv through my samsung phone, I use 3 apps, that have nothing to do with samsung, but do the same stuff as with samsungs's 'product extras'.
This is actually quite good, allows you to quit being all samsung and choose whatever you like. But that is their problem mainly.
