[QUOTE="mm1352000, post: 1190659, member: 82144"] Hello This is news to me. Until now I was not aware of any compatibility problems with Sundtek tuners. Did you tick the "enable DVB-S2 channels tuning/scanning option"? [URL]http://wiki.team-mediaportal.com/1_MEDIAPORTAL_1/141_Configuration/TV-Server_Configuration/02_TV_Servers/3_Scan_DVB-S[/URL] Yes, in most cases we don't set those parameters. Modern satellite demodulator chips automatically determine the correct values. AFAIK only old demodulator chips (eg. CX24116, used by Hauppauge NOVA HD S2, HVR 4000) need the parameters to be set in order to lock on signal. In that case we use a proprietary API to set the values: [URL]https://github.com/MediaPortal/MediaPortal-1/blob/eb07183b52de2f070c0f807f083e645ba74e9cd3/TvEngine3/TVLibrary/TVLibrary/Implementations/DVB/ConditionalAccess/HaupPauge/Hauppauge.cs#L218[/URL] Do Sundtek tuners require pilot and roll-off factor to be set in order to lock on DVB-S2 transponders? (I'd be surprised if the answer is yes. Usually it's only necessary to set the modulation value correctly.) Can you provide an SDK for Sundtek tuner support (DiSEqC, IR remote, MAC address, DVB-S2 tuning etc.)? That code is not used. The actual DVB-S/S2 tuning code is mostly here: [URL]https://github.com/MediaPortal/MediaPortal-1/blob/master/TvEngine3/TVLibrary/TVLibrary/Implementations/DVB/Graphs/DVBS/TvCardDVBS.cs#L298-404[/URL] Here we set custom modulation - and Hauppauge pilot + roll-off - for DVB-S2 tuning: [URL]https://github.com/MediaPortal/MediaPortal-1/blob/master/TvEngine3/TVLibrary/TVLibrary/Implementations/DVB/ConditionalAccess/ConditionalAccess.cs#L886-1071[/URL] [/QUOTE]
