Need help regarding wifi media receiver

hi,
i am a new member of this community. i need help regarding wifi media receiver. i have recently learned how to stream media from pc to ps3 by using windows media player. it is working excellent. now i want to stream media to other rooms also. can you please suggest me any device so that i can enjoy those contents at my other rooms, as i do using ps3? as ps3 recognises wmp, so i have to choose something that recognises streaming from windows media player. i can not buy ps3 for every room. just joking. any suggestion will be of great help. my english is crap. please pardon me. many many thanks.
