Synopsis::

When I autotune the Terratec card I get 100% signal strength and quality. Even though I would wish that I had that it is not the case.

I pasted the mediaportal.log at http://mp.pastebin.com/649014.

So my initial questions are:

* Is this causing any problems when it comes to deciding what channels to store etc. I can see that the Terratec card has stutter at one of the free-to-air channels "TV4 Östergötland" while the Twhinhan card dones not experience the problem. Do they use the same MUX, PID etc?

* Is this a problem caused by my antenna amplifier and if soo any ideas on how to fix this, if I need to?
