[vdr] AW: Problems with DVB-card's 22kHz-Signal

["Bläser, Lars" <LBlaeser@hofheim.de>]

more than 1 year ago i had those problems too, so i took a ozsiloscope and checked the signal and recognised a great differece between the signal of my DVB-s and my Nokia-Receiver
i tested with 2 LNB´s (Grundig Twin, Alps Single) DVB-S with Grundig was a real problem, so i didnt use Grundig anymore, if you buy a new LNB ask for the option to change if the brand you get is not working with your DVB-s(i found that hotbird VIVA Polska, NBC, Onyx is good for testing)
