Hdtv Receiver Great! Can I Use A DirecTV HD Receiver Without A Subscription To DirecTV?

Can I use a DirecTV HD receiver without a subscription to DirecTV? - hdtv receiver great!

I'm running a PS3 and a HDTV via HDMI. I want to buy a surround sound system to on my PS3 and Xbox 360 in my connection. I know that is a receiver for the PS3 HDMI needed between the TV and surround sound. So I wondered if DirecTV receivers, which would be really cheap, so could do so without a subscription? Thanks for the help. Recommendations for surround sound, which would be nice as well!
