Hello, new user here. I have been having a problem that I cannot figure out. I import video from a Sony HC-7 into imovie (latest version) using the standard import function via firewire. For some reason, the import is fine for most of the time and then plays back as double time. Tried using new tapes and it continues. There seems to be no "pattern" so I am stuck. Anybody deal with this before or have any suggestions for what is happening? Thank you.
