Well, there are the consumer versions of editing programs from Adobe and Sony....Adobe Premiere Elements and Sony Vegas Movie Studio.
Both have trials to see if they suit your needs. They may not fit your activation preferences though...that is getting to be quite common.
One that isn't as well known is DVDLab Pro 2 Edit Suite. I use DVDLab Pro for authoring and it is a very capable program in itself. The Edit Suite adds encoding and editing functions. It also has a fully functional trial. But it is primarily for dvd creation, not AVCHD or Blu Ray.
I personally went the other direction from the all-in-ones. I use semi-pro level software, but I prefer specialized software designed only for certain tasks.
