Content of your oscam.conf file
port = 15000@1702:000000;15001@1833:000000;15002@09C4:000000;
The Ports are necessary for EyeTV/eyetvCamd/OSCam to know how to communicate with each other.
The example line above show us how to access for example Sky.de(15000-15003) HD+(15004) and MTV(15005) cards.
If you switch to one of these providers in EyeTV keep in mind that you need to select the according CAID in eyetvcamd to tunnel the port initially.
