What I'd really like to know is are these readreg errors to blame for
all the artifacts in the picture? As I said in my post, my Nova-T can
receive most of the channels perfectly without a single artifact so my
signal must be good enough for a decent dvb card to handle.

Apart from that, thanks to all of you for writing the drivers! I've no
idea how you even begin to make one so I'm very grateful.
