Every single initial tune always ends up with a "no signal" error, but only if the channel is located on diseqc 2,3 or 4. With the word "initial" I mean: resumed from standby or a OS start/reboot. I finally took the time to debug the issue and to my surprise I found out what caused it. It seems like the diseqc command needs to be issued after graphrun, otherwise the call to : int hr = _propertySet.Set(BdaTunerExtentionProperties, (int)BdaTunerExtension.KSPROPERTY_BDA_DISEQC, _ptrDiseqc, len, _ptrDiseqc, len); will fail with a hr code: Hauppauge: SendDiseq returned: 0x8007001F - n/a If I instead re-issue the diseqc command just after the initial succesful graphun, then it's ok, and the diseqc completes without any errors.
