m4v to iMovie and Premiere

Since my computer is in the shop I had to use HandBrake to rip the video from a DVD of one of our events. The goal is to take a clip from this event lasting a few minutes and then make it into a PowerPoint friendly video file.

The rip from Handbrake took so long I had to leave work before it had finished.  The next morning an m4v file was waiting for me on my desktop. I tried opening it in Premiere CS5, but it would only read the first title screen and not the entire video.  I then stuck it in iMovie.  It took over2 hours to uplaod into the program (the video is an hour and seven minutes), but it works.

I now await to hear which part of the video is wanted in a separate clip.
