Where I live in the UK I can theoretically tune to Freeview using either Crystal Palace or Reigate transmitters. In fact only Reigate gives me a good signal and my aerial is directed at Reigate.
However, by default WMC tunes to Crystal Palace. I can use the "Edit Sources" feature to correct this to the Reigate frequencies for my channels, but every week or so, some of the channels become retuned to Crystal Palace. I normally only discover this when a Recording fails.
This has only been a problem since upgrading to WMC 8. On WMC 7 I did need to edit sources originally, but then the channels stayed tuned to the correct frequencies.
Is there any way in WMC 8 to hard code the frequenceis? Or to stop this constant retuning? I have seen that this has been done by users in Australia/New Zealand by editing a file but I don't have enough detail to do that for myself. Also I am unsure whether I would then automatically pick up new channels if I tried this.
Any advice would be most gratefully received.
Harry.

This is called "opportunistic scanning", and you should be able to turn it off by changing a setting in the registry. Looking at my notes, I see that there are TWO registry settings relating to this, but one may be for Vista and the other for Windows 7 (or both settings may apply to both versions of Windows). I had this problem on my Vista system, and set both registry settings to disable opportunistic scanning.aitcheff wrote:every week or so, some of the channels become retuned to Crystal Palace.
These are the registry settings (I have manually split the long lines to avoid silly line breaks; remove the "..."):
Regsitry Key 1
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\...
Microsoft\Windows\CurrentVersion\...
Media Center\Service\BackgroundScanner\PeriodicScanEnabled
If this does not exist, create it as a DWORD and set the value to zero (disabled).
Registry Key 2
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\...
Microsoft\Windows\CurrentVersion\...
Media Center\Service\GLID\DisableActualStreamOpportunisticScanning
If this does not exist, create it as a DWORD and set the value to one.
No, WMC would not detect new channels. So you will need to decide which behaviour is of more importance to you.aitcheff wrote:Also I am unsure whether I would then automatically pick up new channels if I tried this.

Thanks for this! I'll give it a go and see what happens.
