[Hidden-tech] Digital Video Sound Question

[Rikk Desgres]

Will, 

Some Canon cameras have a non standard sample rate. Sometimes they refuse to
lockup. That's what it sounds like in your case. I don't know which models
have this problem, but it plagues Canon. Do you have another application
that can use firewire to load in the video? Sometimes a different software
might have different tolerances for the varied sample rate.
