Mike W: Boxes that have two "F" connector inputs are always twin tuner PVR's, the two sockets necessary to be able to record on one channel whilst viewing another, or recording two channels at the same time, as on satellite reception equipment each device requires its own input from the dishes LNB.
The "LNB out" referred to is only to enable anyone with a twin tuner PVR but only one input from the dish to be able to use both tuners at the same time, as they would loop the "LNB out" into the No2 "LNB in", the snag with doing that being that both programmes being viewed / recorded has to be on the same polarity V or H, that being why individual inputs are required for satisfactory operation.

Mike W.: And as you will probably guess, PVR means "personal video recorder", these as with your previous Sky box only being able to record what they actually receive, and not that they can be used to record from external sources.
If you are thinking on a Freesat twin tuner PVR (HD or otherwise) you cant really go wrong with a Humax brand device.

Mike: As far as your Freesat question is concerned nothing requires to be altered, as both systems are totally compatible with each other as far as the dish is concerned.
I would suggest though that albeit a bother to do, but you should temporarily try the upstairs box in the downstairs position to see if the problem follows it, because if you say that the signal strength / quality appears to be OK then its the only way of determining whether the intermittent problem is being caused by the box, or alternatively by the upstairs connection to the dish, or even the LNB port being used on it.

barry: If you have Freesat installed that's working OK, and you then unscrew the "F" connector from the Freesat box and transfer it to over to the Sky box, then it should receive "Free to view" programmes (once it scans for channels) without having to alter anything, if it doesn't then the box is faulty, or there is an iffy connection on the "F" connector plug.

Bill: Appart from anything Dave Lindsay has mentioned, in general terms boxes that lose channels when switched off usually do this because more channels are being picked up than the devices memory is capable of storing.
You have to start afresh by clearing all settings, this accessed by selecting Menu - Installation - Fist time installation, the box switching off for a few seconds after you have done this, then when the LED on the front panel goes out you can start installation again, as in most cases the problem usually clears after this action has been taken.

David Jarrold: Taking it that you are referring to using the RF2 output on a Sky box to feed through to the Toshiba TV, did you check and make sure that the Toshiba is set on "analogue" to pick up the Sky boxes RF output? also unless you are using a magic eye for remote channel changing its RF1 you should be using.
Sky cannot change the RF channel number on any Sky box as its only the user than can do that, so if you haven't altered anything then carry out another scan on the Toshiba whilst its set on analogue and it should find the RF2 output channel from the Sky box.
This all being said of course assuming that its just not that the connection between both devices that's broken.

stev3c: As you are not that terribly far away from the Sandy transmitter you should beware of the possibility of receiving a signal that's a bit over the top in strength, so purely for test purposes if you have access to a set top aerial you should give that a try, or even a short length of wire (600mm or so) pushed into the inner part of the aerial socket.
The only reason I suggest this test is, that over powerful signals can cause all sorts of odd problems in a devices tuner, this resulting in false indications being seen of the signal strength / quality received.

Martin Game: Yes! as unfortunately that's the case with quite a number of people, one thing you could try though before giving up is rather than repeatedly using the auto-tune facility to capture channels try "manually" entering the Mux channel numbers involved, as sometimes a dedicated entry and scan can capture a channel that's passed by during an auto-tune.
What to do is scrub everything received by either carrying out a scan without the aerial being connected, or alternatively (and better) carry out a factory re-set, then in the tuning menu / manual tune area entering - then scanning - Mux Ch54, storing anything received (if!), then use the same procedure again but with Mux Ch63.
Should by any chance you receive anything, then use the "add channels" or whatever its called on your equipment to regain the remaining channels.
If you have access to an aerial amplifier then this procedure could also be tried whilst temporarily using it, but its a hit and miss operation, as you would also be amplifying the already powerful signals being received from the main BBC / ITV multiplexes.

Sheila: As far as the TV losing programmes is concerned, this problem is in most cases caused by you having received more programme channels than the memory is capable of storing, hence they are lost on switch off.
You have to start afresh by carrying out a factory re-set to put the set back to its original condition when bought, you might though get away with just carrying out a re-scan without the aerial being plugged in, however no matter what method is used, once completed you can then carry out a normal auto-tune.

howard barratt: If your BBC is reasonably good then its liable to be through luck, as the trade view reception predictor (for what its worth!) only indicates mux Ch40 (ITV3 etc) as being good from Hannington, the BBC and ITV as being poor and the remainder as variable.
Crystal Palace, the only other station that's shown as possible to receive, is even worse with only the BBC and two commercial muxes indicated as being possible, but in the category of "poor".
As far as Hannington is concerned the situation isn't shown as changing until April 4th next year, Crystal Palace though still being iffy, as although it gets slightly better it deteriorates again in June.
You are obviously in a difficult reception area, and so only the time consuming exercise of experimenting with different aerial positions is liable to help the situation as nothing can really be guaranteed to work in circumstances such as yours, your snowy analogue reception being a clue as to how bad the signal you are receiving is.
