Steve:
Adjusting the direction of the aerial has no effect on how the digitally encoded signals are decoded. All you could achieve is potential loss of some services. The lip symc problems are due to anomalies within the transmission path and the decoding equipment in the TV or STB not resolving the delay in the sound or picture. Some equipment can be adjusted to resolve such matters, so check your User Manual to see if yours has such an adjustment, but not all do.

At the time you wrote there was no known fault at Mendip. I get my Greeview from that transmitter and have not experienced any problems recently.
However, there is now some engineering work being done, to add some services I gather, and today will see weak signals. That means you may have some problems during the weak signal periods.
That being said, it is uncertain as to whether you are using the Mendip transmitter, Bath has its own 'relay' transmitter. If you give a full post code (or that of a nearby shop or post office) we can check which would be the more likely source.

Richard Cooper et al:
Judging by the number of posts on this subject it may be that a fault has developed either at the transmitter or in the link feeding the data signals to the transmitter. Reporting such to the BBC is a good first move.
That does not counter the fact that some TVs have an adjustment for such delays and these can alter when software updates are sent out.

It is usually because there is a fault that needs to be corrected. Generally, any servicing/maintenance or adjustment work is carried out during weekdays, but occasionally additional work is needed and availability of staff may mean it has to be done at weekends. The staff used for this work also attend to the many other transmitters in the area. As fauklts have to be corrected ASAP, then other work may have to be re-scheduled and that may means some jobs being done at the weekend instead of the originally planned weekday.

Start by looking at BBC - Reception - Help Receiving TV and Radio and contacting them. They may have the answer or may pass you on to someone else as many transmitters are maintained by Arqiva (http://www.arqiva.com/) who also have a Contact Us option. Wotrth talking to them as well I suggest.

When you say you have turn the box off, did you unplug the mains supply as well? If not, then turn the box off using the remote control, switch of and unplug from the mains socket and wait at least 5 minutes - that is to clear anything stuck in the system memory. You should also remove the aerial plug from the back of the box (the one coming from your aerial and not any that may be feeding to a TV set, etc. Then reconnect the mains supply and wait a further 5 minutes. Then turn the box on with the remote control and if possible perform a full automatic tune with the aerial still unplugged. Assuming that process is performed by the now reset box, plug the aerial back in and do another automatic scan. Hopefully, you box will have reset and recovered.
Note that the Goodmans boxes are known to suffer from internal power supply faults and these sometimes show up as a box stuck with a green or yellow light remaining on. If the above procedure does not clear the problem, then it may be that the box has developed a fault internally.

Richard Cooper:
The problem with DAB is that we should be using either DAB2 or DAB+, as 'standard' DAB breaks up badly in many cars as it is not resilient to variable path delays - as happens with moving cars! That is one reason why many stick top FM reception. Another is that many DAB broadcasts are in mono or pseudo 'stereo' which is not good enough for many music lovers. Further, the tonal quality of DAB is considered by many to be not as good as that of FM stereo. It seems to be related to the difference between digitised sound and analogue sound, many not liking the digitised version. It is mainly the music performances that people notice the differences, particularly those involving pipe/wind organs which have overtones that are not reproduced in the digitised version of the performance.

It sounds as if your previous occupant had a Sky dish but not an aerial. To get Freeview, you need an aerial installed to get the signals from the best transmitter for your precise location.
The dish left behind is suitable for use with either Sky (for a subscription monthly) or Freesat. Satellite equipment normally uses a screw-on connector, called an F-connector, for the signal input connection. Some Freeview TV sets also use an F-connector for the aerial input - but it must be fed from an aerial and not a dish. Some TV sets also have a satellite facility which uses an F-connector but is set up separately from the Freeview system.

Further to that said by Richard Cooper, AL Jazeera is only transmitted on HD services now. To get that you need a TV set, or set top box, that is capable of receiving full HD services, an 'HD Ready' set will not be so equipped. Note that not all transmitters are providing an HD service as yet, so if you give us your post code (or that of a very nearby post office or shop) we can look up which transmitter in the Newcastle area you are likely to be using and whther that transmits Al Jazeera.
