I don't think I'd ever trust an auto system to edit for me.
The hardest thing is that you can't 'see' the beat. I found my own solution, as follows.
Open the music in multi track music software - Acid Express is free - and pick out the beat, ONE two three four, ONE two three or whatever. Then get a 'beep' from somewhere, if necessary record a tap of a pen on a desk, anything. Lay the beep on another track where the 'one' beat is, all the way through. Should be regular spacing. (But not always, I find)
Then delete the music track, and save the beep track as a wav file, and you have a visible metronome. Put the beep track on one of the sound tracks of Pinnacle, or any software, and you can see the peak in the wave form, so you know where to cut your scenes. Once you've made the 'beep' track it's easy.
You could set up a metronome to the right beat, and record that, if you have one.
I daresay others have their own ways, which may be easier, but that's mine, for the moment.
Don't cut to every beat btw, you can have some scenes that are 2 or 3 bars long, just make sure when you do cut, it is on a beat. You can't have some on the beat and some not. Either all the cuts have to be on a beat, or the beat is totally irrelevant. One thing or the other.
