Tuner channels not clear/Poor tuning

[dinki]

I was messing about with MediaPortal and it seems like something went screwy with my GBPvr settings in respect to my analog cable tuning. I can see the channels through a lot of snow and the sound is very distorted. This appears to only be affecting the PVR150 MCE and not the PVR150 NonMCE that I have.... The problem appears on most channels, but not all.

I tried running the tuning assistant, and the channels come in crystal clear. The same holds true for autoscanning the channels in Dscaler. Unfortunately, I don't know where I can a) check the current GBPvr frequency values for these channels, and/or b) modify these values if necessary.

Any help would be greatly appreciated..... Thanks.

MediaPortal has probably created tuning overrides in the registry.

Go to:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\TV System Services\TVAutoTune]
and delete anything existing in this key.

That definitely fixed it. You've saved the day! Thanks for the speedy reply!
