I live in IP4 in Ipswich. I have a standard rooftop aerial. I can receive all of the analogue channels and most of the digital but seem to be missing those digital channels on Mux2. Do I need to switch to a wideband aerial?

Nick: Flat panel sets are much, much better than CRTs, and this is often the problem, they show up faults in the picture that are blurred by a CRT.
If you have an LCD or plasma display and find the picture is not as you expect, turn off the "sharpening" feature - and other visual enhancements.
HD pictures are clearly much better than SD on analogue or digital, if you can't see so, then you are probably not looking at an HD broadcast.
Everything on BBC HD is 1080-line HD, but not everything on BBC One HD, Channel 4 HD or ITV1 HD is sourced in HD.

Thank you once again, Brian.
As you can see, I am giving a lot of thought to going digital. A friend who works in the tv repair business tells me two freeview boxes in his house packed up within an hour of each other and he has experience of numerous others not lasting long. Is there any underlying reason for their unreliability, can it be power surges, can they be protected, are some more prone to pack up than others? I do not want to spend several hundred pounds on a freeview tv only for its tuner to pack up.

Thank you for that, Brian. Are freeview boxes less reliable then, and why? Would it be any benefit to plug tvs and boxes into 4 gang surge protected extensions?

Nick: You can get Freeview boxes for as little as £20, sometimes less. They will usually work for two or three years, but they often fail after this time because they are on 100% of the time and the quality of the components is lower.
You can surge protect your equipment - all my computer equipment is on a surge protector that was pulled off a PSBX about 20 years ago - if you want.
UK mains electricity rarely has brownouts, if you had poor wiring and equipment with dirty switches (such as cheap thermostic equipment) a surge protector might be a good idea, if you don't then it would be a waste of money.

Dear Brian,
Thank you once again. £20 is the most I have seen locally for a box, Labgear. Don't suppose you can recommend one?
Can we not switch them off when not watching? Pull the plug? Or would that cause other problems? Presumably the tuners in sets get a rest because we switch off the tv, so they last longer.
Best wishes,
Nick.

Nick: Most boxes and sets have ultra-low-power stand-by modes, but you usually leave them on to allow overnight EPG and firmware upgrades.

Brian, you are being very good answering all these questions. I hope your answers are useful to others.
I assume you cannot recommend a box, but I have seen nothing other than cheap lately.
Sorry to be dense, but say you switch off the box overnight or even a couple of weeks when on holiday, would it not 'catch up' with the info it requires? After all, when they are in the box at the shop, they are not 'learning' anything.
Kind regards,
Nick
