MAPMAN: The loss of Pick TV, Sky News and other on ArqA was expected as it changed channel and increased transmission on 28th March. Thus, a retune was necessary in order to restore it.

When don't display (i.e. "") and it is not caused by a change of by the , then one of the worst things you can do is retune. All you can ever achieve is loss of those services from the TV's memory or they appear as they were before. Thus the affect can only be negative or neutral and this is therefore a waste of time.

Have you considered that it may be too high a signal level and a bit of attenuation could be required? See

Why does the and it's relays transmit ITV on ITV1+1. This doesn't make a lot of sense when the majority of users are in the ITV1 area. Why transmit different stations for ITV1 and ITV1+1??? If you miss the local programmes on ITV1 you can't get them on the +1 . Can anything be done about this ---- and soon?

JohnM: There are less ITV1+1 regions due to the cost of creating +1 feeds for all ITV1 regions. For the same reason there are limited ITV1 HD regions and similarly the BBC does not provide regional BBC One HD feeds.

If missing local ITV1 programmes is that much of an issue, then set them on your PVR and you can watch them back at any time. I didn't realise that there was that much local programming left on ITV1....for cost reasons.

JohnM: ITV plc have recently obtained broadcast licences for ITV1+1 ( and /), so hopefully this indicates they will be launching soon.

Each +1 service requires time-shifting equipment, capacity on satellite, and monitoring to ensure that any content that isn't licensed for timeshifting or can't be timeshifted for legal reasons (for example, the roulette games on The Zone overnight) are blacked out. If something happened in a live event that would cause compliance problems (e.g. a guest swearing) they would want to be able to block that.

The six original +1 regions were chosen to match advertising 'macroregion' boundaries. The limit was six because that's all they could fit on satellite at the time. Now that 1N is in service, there's space for 10, one for all legacy English regions, except for Border which will still get the service. Those regions that still have sub-regional news , e.g. Meridian South vs Meridian South-East, will still have half the getting the 'wrong' service.
