Hi, I'm editing with Premiere CS6 on a 2008 Macbook pro in OSX 10.6.8. I'm using Multi Camera Source Sequences (with two camera angles) and having an issue when setting In and Out points in the Source Monitor. Playback works fine, but as soon as I set an in or out point, the playback immediately has a delay. So the audio is completey out of sync with the video, by a large degree. In fact, I can't even tell as it's so out of sync. If I remove the in and out points, then playback returns to normal. Any ideas as to what may be causing this issue?
