Got a 9150T off fleabay - looks fine. Unfortunately, while BBC channels are fine, most others are juddery/unwatchable. (We've always had issues with poor reception, being in a bit of a valley, but the 9200T in the living room works ok.)
I followed the manual tune instructions, using the channel numbers listed on the DTT site for Crystal Palace - 22, 25, 28, 29, 32 & 34 - and the channels came up unjuddery. Hooray! Except all the channels between 1&8 were missing. No BBC1, BBC2, ITV, Channel 4 and so on. I went back and did an auto-tune, and sure enough, all those channels were found. But most channels had gone back to being juddery. So now I'm a bit baffled. Any help appreciated.
