Thanks. But are you sure this won't result in poorer quality?

I see on their site that this conversion should make the editing go smoother due to lower hardware requirements, compared with directly editing the video in some other program supporting AVCHD.

Though, if another program does it better without conversions etc, I would actually prefer that.. I have one of the new Intel Quad cpu's @ 2.66GHz and 4GB which should handle the editing okay?
In this case, what program would you recommend? Sony Vegas or Pinnacle 12 Ultimate, or something else?
