You have a symbol rate of 6900 kbaud and QAM-256. If my math is right, that should give a net data rate of almost 51 Mbps - considerably higher than the data rates used in German cable and on ASTRA satellite (both about 38Mbps). Considering the not-so-good engineering of both the VES1820 and the AV7110, you should be happy that you got it working at all... :| > Also Martin Neuditschko has these artefacts, but everyone has > it on different channels. > > Where to start? Trying to improve the signal quality might be a good start. Maybe use better cables from the cable outlet to the card, removing or replacing the cable amplifier, etc. Then newer hardware might be helpful - the VES1820 is quite old. Philips has since released the VES1820X and the TDA10021. And the AV7110 is hopeless anyway... So if you can find a card with _current_ hardware on it, it might also give better results (unfortunately, I don't know of any, except maybe for the TechnoTrend hybrid DVB-C/T card which I think will have a TDA10021 as the cable demodulator on it, but it is a product planned for 2004).
