    I've just bought a Thomson DHD4000, and a Philips 28PW6518 television. I
    have a fairly modern ariel, it is a "death ray" sort of liiking thing, which I
    think is called a "wideband" ariel. The ariel goes into the DHD4000, thence
    to the TV, & there's a Scart lead between the two as well. Nothing else
    is connected.

    Sometimes, I get a rather "jerky" picture... it seems to freeze, then resume
    a second or two later (losing what's happened in between times, to the
    eye, anyway). Why might this be happening?

    Codger I have this model also.

    I have seen what you are describing and have always assumed that it is the signal just on the edge of breaking up.

    It used to be much worse (I would lose sound as well fo 1 sec) but I have done everything possible to improve my aerial and it does not happen much anymore.

    I dont think it is a problem with this box particularly.

    What sort of signal strength and quality do you get?

    I get strength 5 qual 6/7. Also it only happens on channels on certain MUX'es as apparently some are more prone to errors. BBC seems best.

    Hope that helps

    Um, I do live in an area where Freeview say I can't get the service...

    Dunno. How do I tell?

    Thanks for your help/reassurance that it's not the box!

    OK,

    I really think there is nothing wrong with the box then. I also live in a postcode that is not officially covered by Freeview but on my estate there is an aerial piped to the houses which can pick up the crystal palace transmitter.

    To see the signal strength for the tuners...if you go to the menu and then (off the top of my head) setup/settings technical help.

    It will tell you how many channels you have found, which transmitter etc. and what the strength is for each tuner.

    But it sounds like its just a weak signal.

    If it is really bad then maybe you should decide whether it is worth living with for freeview. you could alway get free to air satellite system set up for 100 pounds or so and then get a tivo or something.

    The signal strength is generally about 5. The "quality" is about 8. Does that
    tell you anything significant?

    Hmm, "free to air satellite" - ?? Also, "tivo" - ??? Please bear in mind that
    I'm not "up on technology"!
