Oh oh, I think I screwed up on my HTR purchase

[bigmf]

The budget went out the window and I made a purchase on the fly. I got Sound Stage Stage 400 for the fronts. Satge 300 for the rears sound stage center channel and their 10" subwoofer. Powering this is the Onkyo tsxr674. Other components are a Westinghouse 42w2, ps3 and a Motorola 2416 ( i think thats the right number) DVR cable box.

After hooking it all up - bad flicker from the ps3 and green screen from the cable box. I don't know how I missed the ps3 flicker problem on the internet before this issue, Also the on screen display doesn't work over HDMI??? The speakers sound great -no problem with them. I'm thinking I should return the receiver and go with the HK. Anyway to fix these problems or just take it back? I've decided HDMI 1.2 is all I need because the PS3 does the sound processing and sends it to the receiver.
