I just had vios installed and have the psyclone. I have the same problem, not just with xbox360, but with all other component video hooked up exect the fios. If i disconnect the green component lead from the fios (cable) box the interference goes away. Tech support from verizon said it might be from the high level signal coming from verizon and the psyclone is being affected. Hope this helps. He recommended checking the input spects for the psyclone.
