I purchased the VGA adaptor assuming that it would simply show the iPad screen on my TV (which has a VGA input) as would normally be the case. I saw this as an advantage over Apple TV which will only stream media content as I understand it. It looks like I was WRONG. Even the the VGA adaptor is apparently only active while media content is being output. I assume that this is supposedly related to DRM. Is this correct? Is there a third party VGA adaptor that works "normally"?
