I found that my system did not have the dvb-fe-tda10048-1.0.fw file either.
I copied it to lib/firmware yesterday and have not had any pixellation  
events since.
This bug certainly was a can of red herrings.Weird that in my case  
reduction of signal improved the problem.

Many thanks Curtis for finding the real cause of this problem.
