Hi Neil thanks for the post, I'm new to the group and have just tried connecting an iPhone 4s via a similar setup iPhone to male 3rca with USB. Then that plugs into female 3rca to 3.5mm aud port of the is300h. Problem is not the video but the sound. Whilst playing the sound on the phone it all works fine the moment I plug in the USB the video pauses on the phone and I click play only for the sound to play from the speakers for just few seconds and then dead silence. The video playback still plays fine. Any help will be great. Thanks.
