I also have such a card. I haven't observed this yet but i am still
convinced that the channel decoder driver isn't perfect yet. Since
the chip is integrated in the tuner can, i can easily imagine
that there might be a temperature issue. It would be perfect if you
could confirm this somehow.
It is possible to run the channel decoder at a lower clock frequency.
I might modify the driver for 48MHz instead of the current 55MHz and
send you a test version. But this will take some time.
Interested?
