See details below. Again, any hints are greatly appreciated. I *don't* want
Windows on my VDR.

It works fine under Windows using the following config (for CNN):
QAM_64, 6875000 symbols/s, Freq: 354000000 Hz, vpid 4097, apid 4353, service
id 3401 (I think this corresponds to the "pnr" in the linux driver).

I also modified dvb_frontend.c so that is does stay on the same freq all the
time. Specifically, I changed fe_zigzag() to use an offset of zero (soff=0).
