signal strenght with the femon plugin, but I'm not really sure how to

If it is the signal strength, what do I do? Buy an amplifier? Use the
shortest possible cable?

Nothing in the machine except the two DVB cards and an AGP graphics

Tried to fiddle with the PCI settings in the BIOS, but no change.

Not sure. How can I check that?
