I'm not certain I understand what you mean. Maybe it's related to the same kind of error I was getting after a recent update (I updated my 7020HDv2 2 weeks ago). The Dvb-t Tuner suddenly stopped working, I only got an error message. I simply switched the tuners (dvb-t in the first slot, dvb-t in the second slot, and it all works as I was used to... I only have some trouble with the Das Erste HD Transponder which gives me a tuner failed error once in a while).

There might not be a relation, but who knows

But I am not agreeing your statement, that the dreambox team is not making a good image!!!

It's hard to fix errors with posts like this. Latte0815 did report a similar problem and the dev responded. Maybe because he's reporting in a polite way.
