Here is a Video of my Poor mans Home Theater Setup. I have had this Projector for 3 years it is has a little hummm but if you have the stereo up you cant hear it. I play PS3 on here and Xbox, I have a PC connected to my Receiver
I use my Receiver it is a Yamaha RX A2050 it has 7 HDMI sources! You plug your TV into the IN port then you have 7 sources to use for out. I have only had this for 1 year already, it is a dream. If you have an old receiver and you are into this stuff. I say this is a must to upgrade, I put it off until mine broke
I use mine all the time any of the smaller units will work but I am sure all the other brands are the same in how they work.
