Damn, I missed that piece of information when I browsed through those
pages...

Is that information same for every channel? The channel listed there was
subTV which will do nice when I try to test my card. :)

Ok, modify those values and recompile.

Eh? That's so fucking stupid... Then there's two possibilities; different
drivers for every country or some kind of setup program which will save
that information into registry to be used by the driver.

I'm using the Lapua's transmitter (A:38:610MHz, B:55:746MHz, C:37:602MHz).
And that subTV channel is in the B multiplex, if that matters...

Well, if it isn't broken, don't fix it. Right? :)

How long the analog broadcast will continue in Germany? In Finland they
will stop in 2006, or that's what has been planned, I think Digita will
extend that time by year or two.
