I'm talking about the (closed source, but Convergence has it) firmware
that is distributed with the Linux driver. You mean the little extra
firmware that one has to get out of the Windows driver (Sc_main.mc),
where Convergence doesn't has the source.

So it is most likely the same problem I'm facing - but this isn't the
crash I'm talking about. Older firmware distributed with the Linux driver
sometimes made the ARM (the video processor/whatever AV7110) crash, so
that that it didn't handle anything. This happened regardless of the DVB
type (S, C or T).
The problem that we are talking about seems to be specific to DVB-T -
maybe specific to only this special card/tuner type.

This should be checked.

Anyone else seeing this tuning lockup with a DVB-T and doesn't have a
ALPS TDLB7 tuner? (Maybe we should ask this in a seperate thread?)

It might be a problem with just this extra firmware from the Windows
driver. I'm actually thinking of getting rid of this buggy card (see the
vertical lines on the composite out...)

Cheers,
Juri
