I have a Sony HC7 HDV camcorder.
Recently I noticed that if I have been using the computer while transfering teh video through firewire, the resulting video will have macroblockings.
( Like if Im browsing the internet or doing something else ).

Is there a foolproof way to transfer the video from the tape to the Computer ?

( Even if I have not been using the computer it is quite possible that one of the system processes, or virus scan decided to run. )

Thanks
