Maybe faulty data in the NIT?

You could start debugging this by adding some printouts to cNitFilter::Process(),
around line 133, where the transponder frequency is decoded.

I do have an LNB pointed at S28.2E, too, and my channels.conf contains these transponders:

10714,10729,10743,10758,10773,10788,10802,10817,10832,10847,10861,10876,10891,10906,10920,10935,11222,11223,11259,11261,11307,11343,11344,11390,11426,11469,11488,11507,11526,11546,11565,11584,11603,11604,11623,11681,11719,11739,11758,11778,11797,11817,11836,11856,11875,11895,11914,11934,11973,11992,12012,12031,12051,12070,12090,12109,12148,12168,12187,12207,12226,12246,12265,12285,12304,12324,12343,12363,12382,12460,12480,12523,12559,12560,12606,12643

I never had the error message you've posted, though.

What kind of DVB adapters are you using?
