Over the weekend I discovered at least one other channel with frame 
dropouts, though not as much or frequently as the first channel I 
mentioned (BBC Prime). It is  a channel that often has a poor quality 
from our cable provider, even though it's one of the major national 
channels here in Switzerland.

I'll have a look at my cabling as well, perhaps I need to put in a booster..
