Nick: Any set top box that's intended to be used to feed a TV via its aerial socket has to be the type with a built in RF modulator, many of them have this facility built in as standard, although its not always immediately obvious whether or not they do without checking the specification in the devices operating manual, it has to be said that many of the lower end price ranges don't have them for obvious reasons, this also applying to lower priced PVR's.
Separate RF modulator boxes are obtainable from places such as Maplins etc, these being about £20.00 or so.
As far as sharpness of picture is concerned via an aerial socket, it depends entirely on the devices being used, as the picture on some TV's (even LCD's) can appear as being sharper via its aerial over the scart socket input, likewise scart RGB inputs being used (which is technically the best) doesn't unfortunately always give the best picture over the standard composite (CVBS) video input even although its technically inferior.

kevin: As you are only approximately 7 miles line-of-sight away from Craigkelly you could be receiving a signal on the verges of being too powerful, albeit that HD can tolerate that better.
I cant see that you have any option but to try reducing the signal into your TV by purchasing a simple (minimum reduction) attenuator, these only being a few pounds.
There is always an element of hit and miss with these things, especially when using a communal aerial which will undoubtedly have an element of amplification in the system, but unless your situation improves by trying out a further re-scan I cant see anything else you can do.
Although its not by any means a 100% accurate test, but try and find out if any of your neighbours are having problems just in case its the distribution system at fault.

Alice: You havent mentioned what model of Samsung DVD recorder you are referring to, (R135?) but it should be pointed out that just because it has an HDMI socket doesnt mean it can actually record in HD, as the HDMI socket is only an output to enable up-scaling of a normal recording, and not for for the input of an HD signal.
Maybe you could confirm (or not) the model number.

Anne: If you have the Freesat box coupled into the TV's AV1 scart socket input the TV should switch to the box as soon as its (the box!) is switched on, if it doesnt then try pressing the TV/AV button on the TV's remote control as that forces it to change.

Wallace Milligan: Yes, you are pefectly correct, however stopping this happening is not always an easy process, especially if a person already has a roof mounted aerial, as in these cases there isnt that much can be done to help rectify the problem.
It should also be said though that this intermittent blocking can show up much more so if the signal received is just above the recepton threshold, so maye you could indicate what your signal strength / quality indicates when checked in the tuning menu section of your TV.

tom munro: If you can get all channels with the aerial plugged directly into the TV, then that means that doing it via the music centre or whatever is reducing the signal level to below what the TV can operate on.
The analogue tuner will not have any effect as far as the problem you mentioned is concerned.

Neil: There isnt really any ideal channel unless you are using the Sky boxes aerial input socket to feed a Freeview set in another room as well as it receiving the Sky boxes analogue signal.
That said though if you are in the Stockland Hill Freeview reception area then I would try a test using channels from 35 upwards.

Jimmi James: When that happens its usually always due to your signal glitching, this causing a momentary picture / audio freeze, and nothing really connected with the broadcaster, although digital signals can glitch anywhere along the line from their source.

Gill: If the dish works with a Freesat box but not the Sky one then its the latter that is faulty, as the dish responds the same to any satellite box connected to it, irrespective of what it is.

Aaron: In your particular case of being in effect just across the water from Craigkelly you "may" be receiving too strong a signal, the problem being that this can cause blocking of your sets ability to receive properly.
This effect will apply more if you are using a roof mounted aerial or a booster on your system, if you by any chance are then measures will have to be taken to reduce the signal, like by-passing any booster fitted or using an attenuator in line with the aerial lead into the set.
I know exactly where you are in relation to the transmitter, and that's the reason I mention this possibility which may, or may not apply dependant on your aerial arrangements.
