I have the RCA composite Wii cables hooked up to my Yamaha RX-V650 receiver with S-Video up conversion to my Mitsubishi rear screen projection TV. When I play Wii Sports or Wii Play after a little bit, the video goes in and out, goes to black and white, and then eventually loses the signal. Unlike the other post, this happens when I am not using the virtual console. I tried other input sources with no luck. I have since bypassed the receiver and have it plugged directly into my TV input. Have others had this problem? Is there a resolution to it? I have not tried since I did the Wii update the other day. Would this potentially fix it? Is a problem with the receiver? The cable? The Wii? Any suggestions would be greatly appreciated.
