I bought the genuine Apple AV component cable specifically to stream Netflix through my TV. The 30-pin connector is way to big to use with most cases but I thought I would just plug it into one of my non-Apple docks and then plug the iPhone into that. The cable and netflix works great when plugged directly into the iPhone, but it's a no-go when using either of the two docks. No signal. Is there any dock, Apple or otherwise, that will work with the Apple component cable?
