I googled a bit more and figured out, that the Sceneo TVcentral guys
seem to have similiar problems with KNC1 and Terratec Synergy card. They
made a patch which changes "something" with the automatic gain
May this be relevant for the linuxtv-drivers, too? - And what could be
changed regarding the agc at all in this driver?
It seems like the guys from itvmedia.de did some modifications to the
driver, because they don't get the problem (I had a box here and tried
it with the exact same card, that makes the problems in my machine). I
allready asked them to send me their kernel/dvb-sources, but didn't got
an answer yet.
