The ViewNext method finds another input device to view the specified tune request.
This method is supported only for analog tuner devices. It does not work with digital tuners.
HRESULT ViewNext( VARIANT* pv );
[in] Specifies the tune request as a VARIANT type.
If the method succeeds, it returns S_OK. If it fails, it returns an error code.
This method works like the IMSVidCtl::View method, with the following difference: If the system has more than one tuner that supports the specified network type, the ViewNext method skips the current input device and uses the next one. (The ordering of devices is arbitrary.)
