[QUOTE="mm1352000, post: 808144, member: 82144"] Hi again Okay, I'll post as soon as I get home from work. It may conflict with other tuners and getting wide enough testing for the change would be difficult with analog TV being phased out in many countries. I get the impression that there must be a reason for the code - maybe to remove a blank video stream from radio content - however it was added *way* before my time. I'm not opposed to adding it; just conscious that it is a risk. It is not the card manufacturer (Hauppauge) but the chipset manufacturer (NXP/Philips/Trident) that is important since NXP created the driver - all tuner "resellers" that use chips from the same "family" use similar/compatible/identical drivers. The HVR-2200 is based on the SAA7164 chip; my cards (Digitalnow Quattro and Pinnacle 7010ix) are based on the SAA7162 chip. I use the Blackgold BGT3540 driver. Sure! :) [CODE] public ITvSubChannel Tune(int subChannelId, IChannel channel) { Log.Log.WriteFile("analog: Tune:{0}", channel); if (_graphState == GraphState.Idle) { BuildGraph(); } BaseSubChannel subChannel; if (_mapSubChannels.ContainsKey(subChannelId)) { subChannel = _mapSubChannels[subChannelId]; } else { subChannelId = GetNewSubChannel(channel); subChannel = _mapSubChannels[subChannelId]; } subChannel.CurrentChannel = channel; subChannel.OnBeforeTune(); PerformTuning(channel); subChannel.OnAfterTune(); try { RunGraph(subChannel.SubChannelId); } catch (Exception) { FreeSubChannel(subChannel.SubChannelId); throw; } [B]//_encoder.UpdatePinVideo(channel.IsTv, _graphBuilder);[/B] return subChannel; } [/CODE] Comment out the _encoder.UpdatePinVideo() line and you're good to go.
