Slideshow Music problem!!!! It doesnt work like it says it on the box.

Question

I have put together some slideshows and i find every time there is a problem with the fit to music option when i select a track from my itunes library. If i let it run fine it works but if i press fit music to slide show then the track goes into a total slow down and even if i reselect another track it still repeats the same problem. ive tried with 20 slides to 40 slides. So at this point I am certain that this part of the program does not work properly. i see this problem all over the internet so adobe fix it please. Its a simple option so it doesnt take rocket science to press 2 buttons.. but these buttons dont work.  Selling something that doesnt work sends me rushing back to aperture. Anybody else got this problem..u bet. fire the guy who is wasting my time having to write this.

So, are you going to share the solution because I have run out of vriables to play with.
There are a couple of ways to get around this limitation.  The "right" way is a pain.  The "easy" way is potentially problematic.
Bottom line:  The transitions and slide duration boxes only allow precision down to a tenth of a second.  If your song length and slide count don't divide up to an integer of tenths of a second, you can't fix this in the UI.  If they do, it's possible the tool won't choose these properly due to roundoff error.
My suggestion is to select songs/slide counts so they do divide up into an integer number of tenths of a second (that's the problematic part) and then manually pick a slide+fade time to match that.  If you can't do that, you might need to add a tenth to one or the other from what the tool chooses, but then your show might finish just before the song does.
The "right" way is to manually edit the template, where unlimited precision (well, I suspect it's 32 bit floats or something) is allowed.  That's a pain.
Lightroom shouldn't force either solution onto you, but the 0.1s precision is currently the limitation here (not the math education of the team, a few of whom hold advanced degrees in mathematics and related fields).  Hopefully, the team will fix that problem.
