Does anyone connect their touch to their tv? I bought a cable online that didn't work, I bought another at the store and it doesn't work well either. The audio comes through fine, but the video is tricky; it's hard to get the cable to form a good connection. Finally, I broke down and bought the apple dock to use with the cable thinking that I could get a better connection, but no dice. Do I have to buy the apple composite cable as well?
