I too am having a problem with the audio lagging behind video after I down load a VHS clip. I am running an iMac with OS 10.7.5 on a 2.66 GHz Intel Core 2 Duo processor. I uploaded an update that support linked me to. It now says I'm running 2.0.1 version of Roxio Video Capture. The problem still existed after the update. The QT Sync would not load because the computer will no longer support power pc apps. I will try the medium quality to see if that helps. I am glad that these forums exist because it is hard to get much help through their company support.
