Some time ago, I had some trouble with tuning and very high bit error rates with my Siemens DVB-C card. I used the coil with ferrit core and the two potentiometers on the right, lower card edge to adjust the TDA9819. Maybe this will also work with your card. But be careful, the adjustment is not so easy and may not work for your card! The data sheet is here: http://www.semiconductors.philips.com/pip/TDA9819T.html Cheers, Karl
