No the Tack strips have to go through MLV and yes it is a transmisson spot but it is a low traffic area and will not be noticable.
MLV has to be wall to wall and perimeter caulked air tight.
MLV is your sound barrier it has to go wall to wall no gaps.

Since you are in the UK - did you check this web site? http://www.customaudiodesigns.co.uk/products.htm

and here is another UK information source - Probably the best source of the more esoteric info about audio noise and sound info is the alt.sci.physics.acoustics   (This is not a link- it's the address of the usegroup) newsgroup. Lots of good info passing though but may be snobs if not approached with utmost respect for themselves.

I actually bought the mats from Custom Audio but they advised to just put them straight down onto the floor - never mentioned anything about a layer of padding first, which kind of pisses me off since the mats haven't worked. Thanks for the other link, I'll check it out

The mats should work- if they are really MLV and not neoprene (as some have been selling) and if they cover the whole floor, wall to wall with no gaps.

old post as well, but it does give me an idea for how to do a resilent floor, modified from my orignial post at http://supersoundproofing.com/forum/index.php/topic,3465.msg9298.html#msg9298 
First of all, killing your neighbor might only create another problem:  you may end up with another bad neighbor or someone even worse.  Best thing to do there is to retain neighbors who've learned their lesson by going down stairs and headbutting each one in the face.  Otherwise, you may end up with a lust for blood, like what mel gibson has in general. I joke, of course :) about the headbutting thing.  As far as soundproofing while keeping the floor low is concerned, how about this:
cheap carpet pad first, then get some of those cheap 1 dollar 3/8 inch neoprene pads and put them down in a grid pattern a couple feet apart, then on top of those put 1 layer of 3/8 inch osb with more cheap pad adhered to the bottom side of each 4x8 foot piece, seal up the joints, do another layer of osb adhered with green glue and screws (shorties) to previous osb layer and with joints staggered and sealed, then lay the mlv, then rebond pad and carpet.  Am i insane, or is this awsome?  Hard wood floor could even be used.  Might use dimple pads instead of the neoprene ones.

Your on track to an old method we already used.... the problem we found was the durometer was to hard for all the effort involved....Today we have a system we call F-step which 2'x2' tongue and grove 5/8" osb with absorption and a 9 diamond pattern dimple pads which deliver a great IIC.
Most common problem is increased height of the floor but hands down its one of the best solutions.
Not to mention cost..
but never the less, if your going with hard wood floors...this is the best way.
