Over the weekend I tried hooking up my Nintendo 64 to the front ports of the yammy and guess what.....no video but I did have sound. Thinking that the issue was the video cable, I moved the plugs to my TV and low and behold....no issues. I thought great, I have a dead video port on my receiver. I took a camcorder cable and plugged it into the front port then connected my ipod and got picture and sound. So next I tried connecting my camera using the same cable....again no issues. I went back and connected my N64 again and ended up with my original issue.
I thought I might have had an I/O assignment issue. But if both ipod and camera works fine it's gotta be something else.
If you have a N64 yourself, maybe you can try this out too and report back?
Anyone understand why this is happening?
