I'm not sure how Siano's demodulator is working (not to say, I don't know 
it at all) for SFNs.

Your scenario could also be explained with a too strong signal. When the 
ADC is saturated the reception is bad. Especially when not using in-can 
tuners (but silicon ones) you can face the issue easily.

But your problem could also be explained by a 100 of different things I 
don't know.
