That's no way to tune a channel that has decent SNR. It's most likely that channel has a very weak signal by the time it gets to your card. Try to improve the SNR at your card: http://www.ivtvdriver.org/index.php/Howto:Improve_signal_quality > Sometimes, ivtv-tune can't find any signal. > > Here are our specs: > > Dell PowerEdge 2650 w/ 4GB RAM (2 Dual-Core Xeon 3.2GHz) > ATI Radeon XL (Old card but we're multicasting with VLC so it doesn't > matter). > 2 - Hauppauge HVR-1600 TV Tuner Cards In general, I find the analog tuner in my HVR-1600 cards superior to the one in my PVR-150MCE. Is it just that channel or others? Do you have the problem with one card or both? If you work your way back upstream eliminating cables and splitters and have the signal go to one card, how's the picture look?
