Hi i just got the Samsung HT-AS720ST and i'm having problem with hooking the other devices to this system. I want to hook all the devices using HDMI cables. I have a samsung plasma 50'' TV and a samsung DVD player that has HDMI, a HD DirectTV box that also has HDMI, and a ps3. I'm having trouble deciding which would go into the receiver cuz the samsung ht-as720st receiver only comes with 2 output. And i have like 3 devices that need to hook up to HDMI. Please help me !!!!
