Trevor Goldsmith.I would look up inversion effect as the most likely culprit.

Mike,Chatham.You can purchase attenuators from most TV & Aerial retailers as well as DIY stores,the likes of B&Q,Wickes,etc.I would look up the ATV Aerials and Television of Sheffield website as they stock good quality attenuators and i personally only recommend them as such.
As for your mother's Samsung HDD/DVD recorder i would consider resetting that appliance as such as the current memory could be contributing to the pixellations and freezing up during recording.
As for manual tuning if the appliance allows it,is recommended as such,automatic scanning from lowest to highest frequencies often picks up and stores unrequired multiplexes such as weak pixellated ones lower down the frequency band while a stronger one higher up often fails to pick up and store.So yes manual scanning/tuning is the best bet.

Irena Abbott.As JB38 righfully states if you provide a full postcode preferably or a nearby location as such to ascertain reception possibilities at your abode then we can equip you with further valuable advice and assistance.
As for what you described i would look up inversion effect as the most likely culprit as high pressure being currently above most of the UK still can play havoc with digital TV reception as well as what is left of analogue TV in the North East of England and Northern Ireland/Ulster (also Republic of Ireland/Eire) for the remaining 1 month or 2 until Wednesday 24 October 2012.

Durris (Aberdeenshire, Scotland) Full Freeview transmitter | fThursday 9 August 2012 6:58PM
Halifax
Just noticed a slight anomaly concerning the Durris main transmitter page.It is an all group A transmitter but states that to receive all programmes from Durris a group W wideband aerial positioned horizontally is required to receive Freeview.
Should that read a group A aerial instead,as group W wideband aerials have a poor response on all group A masts in poor/marginal areas.

Peterc.Waterlooville.What is the colour bung at the tips of your aerial (check during daylight hours) if i may ask ?
Is it a red tipped group A aerial or a black tipped group W wideband aerial ?
If it is a group W wideband aerial then from your abode to Rowridge (all group A mast) at more than 20-25 miles officially a poor reception area,you are using the wrong group aerial for this transmitter as group W wideband aerials are less sensitive to group A frequencies and on an all group A mast even less sensitive further still,performing poorly as a result which is why group W wideband aerials should never be used on an all group A transmitter in a poor reception/marginal reception area within its transmitting range.
Only group A aerials preferably should be used on an all group A mast,although group K aerials (grey coloured tips) can be used as a alternative except in marginal areas.

My ITV/C4 Freeview channels have disappeared - what can I do? Friday 10 August 2012 11:11PM

Sandi Kitchin.Yes as an anti-cyclone (or high pressure) is over much of the UK as present atmospherics is the likely culprit.
Look up inversion effect for full details !

Mazbar.If this helps,Steven in Liverpool as the postcode L15 4LF which is Picton Road,Wavertree area of the city.
Steven,i would look up inversion effect as a likely culprit due to high pressure !

Irena Abbott.The only solution to reception difficulties due to the inversion effect in mainly anti-cyclonic conditions is to leave well alone and let nature take its course.
Sometimes if you were to rescan in atmospherics you could end up losing all your current channels set up and instead gain short term distant alien (not the ET type) transmissions which often dissipate soon after often within a few minutes.
You can always take a gamble with risks involved !

Susan Ash.In reply to your text dated from Wednesday 8 August 2012,4.09pm,the question you raised in the second and last paragraph is a tricky one for me to answer to,but i will assume that the most likely event to your question would be a 50-50 situation in that the powers that be most of the time will listen to everyone's concerns but again most of the time they will not.
