Nick: No, the RF modulator referred to is simply an external box that takes the place of an internal modulator.
These external modulators usually being fed from either the scart or composite video (CVBS) output sockets on the device that doesn't have the modulator, or anything else if it comes to it, like a DVD etc.
Pictures can sometimes appear better via an aerial socket (on some sets) for another reason, this being because anything fed into a TV via the aerial socket goes through a lot more processing than what it does via the same devices scart input, the auto gain circuitry etc associated with aerial sourced inputs resulting in a more consistently evenly balanced picture that doesn't suffer from the same level of variations in brilliance / contrast on changing scenes, this unlike what is sometimes witnessed via scart connections, or even worse using RGB connections.
All said though totally dependant on the particular type of analogue TV being used, and whether or not the CRT has started to go downhill emission wise.

Bruce: In some cases that might apply, but in my experience not that common and once again dependant on the particular TV or STB being used.
A test that sometimes works if doubts of that nature exists is, go into the devices tuning menu - signal strength / quality check area, once there keep observing the indications whilst the aerial plug is "very slowly" removed from the socket, if just at the point the plug leaves the socket the strength / quality indicators zoom to the top of the scale before collapsing to zero, that could indicate the possibility of an excessively strong a signal.
It shouldn't be taken as a 100% accurate check though, as it can be dependant on the actual set its being tried out on, but in general terms if a signal is grossly excessive then sometimes a signal indication can still be seen with the aerial plug "fractionally" (a hairs breadth) removed from the socket.

Alice: Thanks for the info, and which unfortunately confirms what I suspected, insomuch that the HDMI socket is purely an output for up-scaling purposes of normal DVD's etc, as the device itself is not an HD capable one.

sparky: Anyone that wants to use speakers connected to PVR (or set top box) can only do it by using active powered speakers of the type that's used with PC's, these seen advertised everywhere at very reasonable prices.
The speakers in question would be coupled into the two (L&R) phono output sockets seen on the rear of the box.
Would advise though that you look around for types that offers some form of tone adjustment on them, as the tonal quality obtained from line output phono sockets can be very flat, this basically because the output is really intended to be used into a proper (but simple) home cinema system, which of course always has the facility of being able to control the bass & treble response.

b.Lording: Its really quite impossible to say without making checks on the transmitters involved, this not being possible without knowledge of your location.

Barry: The spec I have seen on this model suggests that it is a Freeview only model and as such will not work outside of the UK's digital terrestrial network, this unlike a Freesat model which would do.

David Martin: If I could just add to Jm F reply to you by asking what brand / model of HD box you have fitted in the bedroom? and when you say "not switched on" are you meaning the wall socket switch or on the actual box itself? as on some models there can be a difference between these two actions.

Barry: In that case you "may" have a problem as I am not acquaint with that version, the reason for the problem being that the BBC HD service on Satellite made a technical change to the method of transmission on the 6th of this month (ref:link below) this being something which has caused problems with quite a number of devices, the unfortunate aspect about it being that in some cases its not a rectifiable problem.
You will need to contact the supplier of your set.

Mary: Its not really easy to advise on this when you omitted to mention your location, as your reception possibilities cannot therefore be checked on.

Brian Goodwin: Re: BBC-HD glitching every 30 seconds or so, just out of curiosity does the other HD services (ITV1-HD / Ch4-HD) do similar?
This said assuming that when you mention other channels as being OK it's normal Freeview you are referring to.
