There was a modified TV Library DLL for MP1 in this thread Digital Devices: cascaded CAM support, that works perfectyi with cascaded cams and DD Octopus CI Pro S2. Morpheus_xx made a patch of these DLLs for MP 2.1 here Digital Devices: cascaded CAM support . Unfortunately these DLLs do not work with MP2.2. Is it possible to create a version for MP2.2 TVE3? In native TVE35, this card only works with one active cam.
