I recently purchased a Samsung MHL adapter. It works great except for two things: 1) The phone doesn't charge even if the adapter is connected to power. 2) (and more importantly), the video lag is unbearable. When I start watching something (Netflix, e.g.), the video and audio start out in sync, but the audio slowly creeps ahead of the video and within a few minutes there is a lag of at least 5 seconds (meaning the audio and video are 5 seconds out of sync). It's really annoying and I can't figure out how to solve it. Anyone know a solution, or have the same issue? Thanks much.
