    Like several other readers of these fora I purchased a Panny 75. My question is...

    Does anybody else's suffer from picture judder (including momentary loss of sound at the same time) when playing stuff back from the HDD. If you "rewind" and play a skipped bit again it'll be fine so it's not the recording at fault.

    If this is deemed to be "normal", Panasonic can have it back

    PS: It's also horrendously slow to power-up

    Not when turning on from the remote so I'm assuming you mean from turning it on at the mains.

    It's designed to left plugged in all the time, so maybe a quick start up time from power on was not a priority.

    oops, I did actually mean when turning on from stand-by using the remote. There's an awful lot of HDD activity before it lets you change input/channel/record etc.

    Are you sure it is HDD activity?

    Make sure the DVD disk tray is empty- That slows down start-up considerably whilst the DVD disk initialises - especially if the disk is difficult to read.

    Otherwise it sounds like you may be suffering from Hard disk fragmentation.

    Reformatting the drive may help but unfortunately would mean losing all your HDD stored programmes.

    Mine only takes a few seconds to come on (and you can change channels straight away). It takes a few more seconds to be able to bring up the HDD Navigator.

    I just connected an HDMI of the first time, and I've noticed it is much slower (though still only a few seconds) than with a SCART alone.

    Hi Gavtech, I seem to have read 100s of posts by you.

    It's really slow with or without dvd in it. I've only had the thing a few weeks and as yet have only recorded 4 programs on it (I have Sky+ which isn't full yet so I haven't needed to archive anything yet)

    I suppose we need to be clear about what a 'long time' is.

    These are software driven devices so it does take a fairly long time for them to 'boot up'

    Can you give a rough time estimate of how long it takes from switch on? ... and how often are you suffering this picture judder problem?

    To eliminate the possibility that it might be a freeview reception problem, can you record some analogue channels and see if you suffer the judder problem on those recordings?

    Start-up time is 25 secs (occasionally longer).

    The picture judder is not Freeview specific as it occurs on a recording made when I transfered a video to the HDD, also a programme transferred from Sky+ and a recording from Freeview. Also, when the picture judders if you rewind and replay the same segment it doesn't judder - so it definitely seems like a playback issue rather than a recording issue. The judder occurs about every 8-10 minutes.

    Mine does not do the judder or the slow start. So, take it back and get a refund or another one (they are good really)

    I think you're right - time to return it.

    Out of interest how long roughly does yours take to wake-up from standy-by?

    The picture judder definitely should not be every 8 to 10 minutes.

    I almost never get it at all - but when I do and replay the same segment, the judder is still there: indicating something happened during recording.

    AFAIK, you shoudnt have any judder at all during caused by the playback itself.
