hi everyone, I just have a few questions about the apple composite AV cable. Hoping you guys can help me out... 1) Will I be able to connect to a stereo system using this cable? 2) Is it compatible with the iPod Nano 3rd generation and the iPod Touch 2nd generation? 3) I often connect my iPod touch to my home theater system using the 30-pin to USB cable. One thing I noticed is that when I connect it, the volume bar disappears from the iPod. I like this feature because it means that I only have to adjust the volume on my receiver. Will the composite AV cable work similarly?
