Retrieving tuning parameters from the BDA Driver?, using FireDTV-S Options

[Thomas Franck]

Hi..!

I'm successfully submitting the tuning parameters to the DTV via the Nodes in the TunerDevice using the IBDA_FrequencyFilter and IBDA_DigitalDemodulator interfaces..

At least now that I stop the graph before making the changes it would let me CommitChanges() without coming back with an error..

My graph looks like this:
[NP(my own dummy)]->[FireDTV Tuner]->[FireDTV Receiver]->[Null Renderer]

After tuning I check for Lock & Signal and for every transponder I tune to, I get Lock@74%(+/-1%).. so I assume it's just pretending to tune and gives me the same transponder every time..

So I thought I would go for the get_XXX Methods of the Interfaces and check what the FireDTV has tuned to.. however, this leaves me with E_NOINTERFACE ..

How do you guys check the tuning parameters? Help is appreciated..

Cheers,
