In the past two weeks we have been getting poor HD reception (pixilation) on all HD Channels, this sometimes includes a complete loss of picture and the notice ‘No signal’ but almost instant correction, also the notice ‘Audio device buffer under-run’ or similar. This also includes Sky News.

All other Channels no problem.

I have had my 1000s which has been working with no problem since bought new about a year.

Anyone else having/had similar problems? the HD channels have been perfect until now.
