I went a different route and hooked up the fire a number of different ways.  I went...

1. Wireless with iptable DNS rewrite on a DD-WRT router
2. Wired with iptable DNS rewrite on DD-WRT router 
3. Wired with getflix DNS on the Fire TV using Telecom supplied Thomson modem.

None the above solutions gave me anywhere near the Netflix streaming performance of the Roku or the Chromecast.  The Fire TV would stream in SD for a good 5-10 minutes before, sometimes, getting up to HD (720p range).  It's frustrating because it seems everyone else on here has had an excellent experience with the Fire TV and I have a Roku and Chromecast which both stream Netflix in HD in under a minute.

I also tried side loading the official Netflix app for Android but I couldn't navigate using the fire remote.

Ah well, I'll hold onto it for the short term and see if any Netflix app updates come out that might make a difference.

Update:

My Netflix country is set to UK (because I prefer the UK shows, as do the kids).  Anyway I switched Netflix to USA and what do you know everything starts streaming beautifully and quickly in HD.

My Fire TV is linked to a US Amazon account so I might try creating a UK Amazon account, switching back to Netflix UK and seeing if that improves UK Netflix streaming.
