There you go Alex, you've got an official reply to your query !
Haven't noticed anything at this location (BT37) recently although, I did have some breaking up/freezing over the Christmas period (weather conditions maybe ?).
I assume BT30 is in and around the Crumlin area ? We have friends in BT 29 and they've had no problems.
Roll on Nov. 2012 then, when all this will hopefully be sorted (along with the arrival of Saorview Lite !)

I am using a Bush HD freesat box and a Luxor HD freeview box with my 'Polaroid' HD ready tv. The freesat box automatically sets to 1080I and the freeview box to 720P. Both are connected to the tv using hdmi cables.
Picture quality on both is very good and if anything, better on the 720P freeview channels.
However when I view HD programmes on freesat (don't have freeview HD here yet)I struggle to see any improvement in picture quality.
Am I alone or just doing something wrong?
Despite this I am very pleased with both boxes, much more fun than the SKY package I had before.
By the way I tuned in ITV HD in Crumlin (northern ireland) with no problem and no change of post code.

Phillip: The HD channels on satellite are at the same bitrate and resolution as those on Freeview. You should see no difference at all between Freeview HD and Freesat HD.
You should clearly be able to see the difference between SD and HD..

There is an article in our local paper stating RTE is going to be broadcast on UK Freeview from Divis later this year. Is there any truth to this and how will this happen??
It does not mention Limavady transmitter which is strange.....

I have great problems receiving MUX2 channels in either belfast BT71PT, or whitehead BT389SP areas. Can you please advise what I need to do to recieve these - I'm using an aerial direct into a new Panasonic G20 viera with free view built in. Please advise
