    After having problems with my 9300T recordings like picture jumping and sound missing I fitted a new hard drive. All went well and now building up library of programmes to watch later. Now I’ve started watching recordings I’m having the same problem with some programmes. At points during playback there can be a slight jump in recording and then sometimes the sound is not there. If I stop the playback and restart it sometimes corrects it but not always. I did a full reset when i first had problems Any one have any knowledge on this please.

    Are these problems on specific series of programs? There is (another) well known problem with the 9300T that on specific programs you get exactly the symptoms you describe. My theory is that the programs in question are using a type of encoding that was not common when the box was launched and as Humax have been aware of this problem for a long time and have not issued a fix, I speculate that the problem is in the chip that does the decoding. As far as I know only the 9150T and the 9300T are the only Humax boxes affected.

    It doesn’t happen with all recordings. I know for a fact it affects Vera recorded Sundays on ITV

    The skipping was first noticed on Family Guy many years ago and still affects Family Guy even though the programme has moved from BBC3 to ITV2. Also there is something in the data of Emmerdale and Coronation Street about 15 seconds before the end that causes skipping on my partners 9300.

    Yes I have noticed the jump sometimes at the end of Coro.

    Hi. I’ve got both a PVR9150 & a PVR9300. Over the last couple of years I’ve also had problems with sound/vision skipping on mainly commercial TV programs but has started doing it more often and now on BBC programs. You’d of thought that others would have found a solution from Humax by now.

    My guess is that the problem is in the decoding chip which I assume can’t be fixed by a normal software update.

    Strange. I’ve had problems with BBC programmes for years. eg. Have I Got News For You – when a missing words style caption goes up. I never used to have problems on commercial channels – but in the last couple of years I’ve noticed it on ITV.

    As for Humax fixing the problem “You got two chances mate: Bob Hope and no hope. And Bob Hope’s dead.”

    There is no know answer to the problem other than to put with it or to buy a new PVR.

    Martin,

    The DTG claim they test all of the receivers they have been given and I suspect they have a 9300T. If this is a problem with the decoder hardware and I also suspect that is, having suffered from this repeatedly (and frequently having to resort to I-player). Broadcasters should know this from monitoring sites like this as should the BBC. Frankly I believe that the fault for this problem lies with the Broadcasters, who should not be using coders that cause this problem. Red Bee or their successors use the coder that their customer (e.g. the BBC) dictates. It happens far less often on Channel5 which I believe does its coding separately from ITV and Channel4.

    In the bad old days of VHS recorders the BBC refused to use some of the features of the Programme Delivery Control (PDC) system because not all recorders had implemented them properly. This caused mis-operation of compliant receivers because data was sent incorrectly when programmes changed but they had checked. Today the BBC just don’t take that amount of care.

    Using codecs that people can’t use is just the same as changing to DVB-T2 for PSBs, which they know not to do. It is just a matter of scale.

    My guess is that they tested the codecs that were in use when the box was launched and later broadcasters began to use the problematic codec. Humax have always been very quiet about this problem which leads me to suspect they knew from fairly early on it couldn’t be easily fixed. As far as I know none of the other Humax models suffer from this problem.

    Well I once asked the DTG if they retested when the standards changed and they said yes. However, like you, I didn’t believe it.

    In my view it doesn’t absolve the BBC from making an effort! Glad to hear you confirm that none of the other products have the fault because I am about to get an FVP-5000 because the complaints about this problem from the other half of the settee are no longer tolerable! Moving the backlog of recordings, which I assume will play correctly on the new box, will now be the next issue.
