Briantist: I'm used to using BBcode which might not be correct for your boards, although my post at 3.56pm see to have corrected itself, I guess you may have script that runs periodically and puts such things right. Just posting the url as part of the text doesn't make it clickable though, and I generally like my links to be clickable, sometimes with a word name - "here" is one of the most common examples one likes to use.

Tom: that's OK glad you've been able to find out what's going on. Always best to use high quality double screened (Satellite type) coax.

Hi Lisa: as Steve P has already said you may have too strong a signal and should take any booster/amplifier out of circuit.
But the other thing you ought to do is a complete new installation/factory reset first with the aerial unplugged - this clears ALL previous settings, & then repeat that with the aerial plugged in.
If you and your neighbours are in a block of flats using a communial aerial you will probably need to get onto the landlords to get it sorted.

Hi Suzanne: There are no problems with the transmitter and the switchover went fine.
If you are using any form of booster/amplifier you could have too much signal take it out of circuit and try again.
It's always best to then do a full factory reset/New Installation first with the aerial unplugged - this clears all previous settings. then repeat that with the aerial plugged in.
Let us know how you get on.

Suzanne: Also do you have a video recorder (or sky box or similar) plugged in, if so bypass this whilst doing the resets & retune.
It's possible the RF out from these may be set to a channel that is interfering with one or more of the MUXes that Oxford is now on, you may need to change it to a low channel eg 21.

Hi Paul Strutt: If you are receiving Sutton Coldfield your aerial should be pointing NNE with the rods horizontal.
If you have a booster/aerial amplifier you may now be getting too strong a signal, Try taking it out of circuit and then doing the full resets/scans again.

Hi Glenn: You have a choice of around 5 Transmitters where you are, so it depends which way your aerial is pointing and whether the rods are horizontal or vertical.
Your best signals should come from Waltham or Sutton Coldfield the latter being the strongest (West Midlands). In either case the rods should be hozizontal, Sutton Coldfield to the SW and Waltham is ESE. These are the only 2 transmitters that will give you all the MUXes.
If your aerial is pointing at the local Derby transmitter (WNW) this will be part of your problem. Which ever way it is pointing this local transmitter could still give a problem as it's BBC channels are in the same band as Sutton Coldfield (Group B). If you're using a booster/amplifier this may add to the problems giving too strong a signal.
Make sure you do a full factory reset/new install with the aerial unplugged from the box/set which will clear all previous settings. Then do a manual install without any booster/amplifier depending on which way your aerial is pointing as follows -
For Waltham (East Midlands) C61, C54, C56, C57, C29, & if it's an HD box C58.
For Sutton Coldfield (West Midlands) C43, C46, C45, C39, C42 & for HD C40.
If your aerial is not pointing at either of these with the rods horizontal, post back with details.

Pete Turner: Hi, most of your question has been answered by Steve P. & mst. Aerial postion can make a difference, as can the +/- shift off the centre frequency, this being receiver dependant - not aware of any specific issues with your PVR, it's a Vestel clone - you can always google, but there's lots to read!
If there is a significant difference between C53 and C60 it could indicate degraded aerial (if old - water getting into connector box could cause this) likewise degraded (or cheap) coax or maybe aerial is a group B instead of C/D. However if you are going to replace your aerial in the future you should go for a wideband to cope with projected new COM muxes 7,8,9 sometime after ~2013.

Karen: check if your neighbours have/had the same problem. If so it'll be something to do with the communal system, possible something simple like a fuse! but you'll need to chase your buildings manager to get it sorted.

Sean:
You could be getting Too Much signal now, especially as you are getting in a number of other transmitters. Try taking your booster out of circuit and see what you get.
