I just upgrapded from a PPC iMac G5 to one of the new Intel iMac's when I try and capture video the sound option is dimmed. What's up? I'm using versions 2.1.1

Hello onegoodmove,
Sorry for your frustration. If that "Mac audio track" option is grayed out, try downloading and installing for the latest version of Snapz from:

The necessary files are not transferred when using Apple's Migration Assistant. Hope this helps
