I will have to wait for the results from DST-CI too, as well as get to

Not all tuners are STV0299 based.. Only a few of them are STV0299 based.

There is quite some more work to be done, before the signal processing

Frederic Cand a few days back, but in a different context regarding the
CA interface. I was tracing what was in rxbuffer at that time.. This
used to create some problems, in certain conditions..
