i'm not sure this is the right place to post, so please redirect me if the post is errant:
i'm using FCP 5.0 on a MacBook Pro. i just recently upgraded to OS 10.5 and FCP (which is the same version as before) is acting a little weird. when i digitize, it gives me this new window called "Analyzing DV Audio" and inside it reads "Validating Audio Data." it takes anywhere from 1-10 minutes depending on the clip. it appears once capture is complete. if i press cancel, the clip evaporates as if i never captured it. if i let it do its thing, when i play a clip captured with in and out points ("batch capture") i lose sync (sound trails about a second behind image). but when i capture on the fly ("capture now") the clips are in sync.
