Catchin' SYNC allows you to capture and manually determine audio SYNC issues of your video playback device. In almost all cases, where audio and video playback passes through separate devices (i.e Audio through receiver, video through LCD TV or Projector etc.) there will be advancement or delay on the audio signal, making the viewing experience unpleasant. Catchin' SYNC will help you determine if your system is in SYNC or not and by how much in milliseconds or frames. With that information you can add appropriate amounts of delay to your signal and get everything play along properly in SYNC.
