My gut feeling is that these problems appeared around when AC3 bitstream out came into DVB firmware,
and I think that was done by Werner Fink.
I think he has kept knowledge by himself, so maybe he should be able fix the situation?

(this is the first new type of firmware(is it?), and was already tested by you)
But this is a feeling, not a fact. So maybe older default firmware for old type of driver
should be tested, I mean not dvb-ttpci* type of file, I mean Root & Dpram -files.
