I won this cool dock (iTube ValveDock with Speakers) in a contest. The dock works perfectly and I can control the touch with the remote and play songs on the speakers. My problem is that I can't get the video output to work on my tv. So is it possible that the ipod touch TvOut isn't supported by the dock ? The manual is not clear about that. Or maybe it's the cable I used (a simple rca cable from the dock to the tv)?
