I did some testing on this earlier today and that cable by itself may not display a picture on your lcd tv at all. I have no idea why, i'm not a technician. I hooked my duo-r up to my lcd tv first using the composite cables, then the scart to vga cable without the scaler, then then scart to vga with the scaler. without the scaler that the cable was built to work with, there was no picture. Also the scaler does in incredible job of taking the picture and smoothing it out without any loss of detail. using only the composite cable i can scale the picture full screen if i want to, but it looks like my cat barfed on the screen. The jamma scaler and scart cable may be expensive, but the picture quality on modern lcd's is excellent. Keep in mind, i'm an amatuer at best, so ultimately steve will know way better than me, just be warned that some cables options may not work were others will.
