    When I record a terrestrial tv station (through aerial) to HDD in SP mode, on playback the sound drops off for about a second. This happens maybe 2 or 3 times per hour of recording. There's no loss in picture just an annoying stutter every now and again.
    I've re-formatted the HDD, had my aerial, leads, etc checked and am running power through a zapcatcher with an emi filter. Marginal reception has been suggested but the TV tech reckoned reception was fine. There's no sound problems when playing commercial DVDs. Help ...!

    Microwave or freezer starting up? Some sort of outside interference. Something connected to one of the scart sockets giving out some sort of control signal? Perhaps a Qlink connection is in operation or one of the devices thinks there is. Maybe its getting a infra red signal from one of your other remotes that causes it. Does it effect all stations you record? Recorder over heating?

    Still sounds like marginal reception, did TV tech check signal levels ?, should be around 55dBµV-70dBµV by memory, if on or below the lower end, electrical noise can cause mometary muting and is not a defect of unit.

    TV tech didn't check signal levels as far as I know but reception is really quite good. He removed surplus aerial lead in the wall cavity and replaced wall to DVD aerial lead. When I watch TV through the tv tuner there's no problem but when I switch to AV and watch a TV programme through the DVD I notice the stutter then. I'm starting to think some other appliance(s) is causing this this as suggested. If it is the fridge cycle, washing machine, lights on and off, etc. it there any way to remedy this. I was told a zapcatcher with an emi filter would prevent this.

    That may clean up mains noise but does help aerial induced noise spikes, yout antenna cables may be running close to some mains cables and picking up garbage noise and the minium muting time on E85 is around 1 sec on audio, which can't be disabled as is controlled via serial bus.
    So I guess back to square one, I can only suggest specialised antenna company are the ones capable in this area, most TV techs just look at the picture and say yup, looks ok to me
