[QUOTE="mm1352000, post: 829933, member: 82144"] Hi again Spooky Happy new year - I hope you are well! :) I'll get straight to the point: this looks like a *really* nasty problem. I'm not sure if it is a TV Server problem or a TT driver issue or a TsWriter problem or something else. What seems to be happening is a DirectShow crash when the graph is stopped: [CODE] FilterState state; ((IMediaControl)_graphBuilder).GetState(10, out state); if (state == FilterState.Stopped) { Log.Log.WriteFile("dvb:StopGraph filterstate already stopped, returning."); return; } Log.Log.WriteFile("dvb:StopGraph"); [B]int hr = ((IMediaControl)_graphBuilder).Stop(); // CRASH HERE!!! :([/B] if (hr < 0 || hr > 1) { Log.Log.Error("dvb:StopGraph returns:0x{0:X}", hr); throw new TvException("Unable to stop graph"); }[/CODE] To me at least it seems like a very odd way and place for a crash. I mean, the EPG grabber had been scanning away fine and then suddenly this particular time it can't stop successfully (!?! :S). My understanding would be that any filter in the graph (including the TT tuner and capture filters, TsWriter, and other Microsoft filters) could cause the crash. The last line in the TsWriter log is: That indicates that the graph was in the process of stopping. TsWriter had been asked to stop... but it doesn't mean it had successfully stopped - there is other code that executes after that. It seems most likely to me that this is a problem with TsWriter (again :() rather than with your tuner. However nothing is really out of the question. I do doubt it is a hardware problem. Is the problem reproducible? [USER=117602]MSlater[/USER]: have you posted logs anywhere. Might be good if we could take a look, else we can't do anything about the problem. mm [/QUOTE]
