You already know how to select the source programmally. That is what the capGetDriverDescription() and capDriverConnect() functions are for. Despite their names, they enumerate/connect *devices and drivers*, not just drivers alone. Even Microsoft says that to connect to a particular device, you use these functions. Alternatively, look at the capSetMCIDeviceName() macro. This works only if you are using MCI-enabled devices, though. Alternatively, maybe you can look at using DirectX instead - specially, DirectShow. Gambit
