Here's a crude representation of what I've got at home:

floor 2     INTERNETS ---- MODEM/ROUTER ---- MY COMPUTER
                                |
floor 1                   WIFI REPEATER ---- stuff
                                |
floor 0                    more stuff        TELEVISION

Now, as part of our sat tv subscription we can get an additional service if we connect our decoder (located by TELEVISION obviously) to the internet. What they suggest is buying a Netgear 3DHD WIRELESS HOME THEATER NETWORKING KIT holy shit isn't my bullshit-o-meter flying high right now from the general buzzwordyness of this thing.

What does this thing actually do that our existing wireless-enabled routers don't do? What's the point of having a third wifi router in the same house, this time only for one television? If I do decide to plunge €99 for this, should I connect it to the wifi repeater (which does not provide AAA quality internet, at least for all gaming purposes) or to my modem/router (risking issues with low signal?).

I will make this answer short.

I see a couple things your typical $150-200 router does not have.

The first is the following:

802.11i (WPA/ WPA2–PSK ), 802.11d, 802.11e (WMM), 802.11h

I would have to look up what standards these are exactly but these are not supported by your typical home router.

The second thing I noticed was this:

Superior WiFi video reliability using advanced technologies Transmit beamforming Space-time block coding (STBC) Channel state aware WiFi link management using real time spectrum analysis

Of course this also might be a glorified QOS.

While 300 Mbps is actually one of the slowest rates Netgear sells the 4x4 radio actually makes it decent.

Wireless: 802.11a/n 4x4 access point or bridge - auto rate capable up 300 Mbps

Of course the Netgear R6300-100NAS AC1750 802.11 which is only an extra $50 has 4x that and supports 802.11ac. In the end this is a fancy repeater, they are $50-60 routers being sold two to a kit.

I don't know how faster your current repeater is, I can tell you that this would replace your current one, and it likely would be faster then your current one. Of course I would not purchase any ranger extender that didn't match my current router.

How can it replace my repeater? The graphic clearly shows it needs to have a wired connection to my router. –  badp Jun 29 '12 at 11:32
    
It has ethernet ports on the back of it. Click product specs on the same webpage you just linked –  VBwhatnow Jun 29 '12 at 14:00
    
@badp - The product you link to is 2 repeaters basically. Look at the diagram they provided. Like I said it sounds like you should just purchase another repeater ( same model as you already have ). –  Ramhound Jun 29 '12 at 18:35

Its just marketing jargon. "Wireless home theater networking kit" translates to wireless bridge in Network engineer speech.

This review actually clarifies things a bit
