I have an R15/500. In the setup there is a tab for TV RATIO. Changing it from 4:3 to 16:9 does nothing to the output seen on my new HD tv no matter what I change the TV aspect ratio settings. It did nothing on my old CRT tv either. Note that on the TV there is no s-video input. Only HDMI, component (three color) RCA, and plain (yellow) RCA video. I am connected via the single yellow RCA input. I will be getting an HD receiver soon so this will be a moot point. But I was hoping i could see the 16:9 ratio on my new TV from the R15/500 box. Is this possible or not?
