I'm starting to transfer my VHS tapes to digital format -- for the first time.

I'm using a Canopus ADVC300. The clips in iMovie work fine, both audio and video, but the 'export' of clips to 1 QT movie fails to export all the audio.

In my clip viewer, I have 7 clips that add up to about 41min.
Audio from the first clip plays but none thereafter. All video works.

I've tried various share settings but no luck. Can someone tell me the best way to do this?

I have searched for an answer but have not found one for my particular situation.

Thanks in advance!!!
