Simultaneous 4 channels, what do i need?

[qwqwek]

Hi all,I am planning to setup my own PVR system and want to get a satellite connection. I have 4 tv tuners which can take composite/svideo input. Can a dish output 4 streams simultaneously? I guess i will need 4 set-top-boxes. Is there anything else which will be required?ThanksPS: i am a dvb-s noob.
