398 STOP_RECORDING:DTV Program::DTVProgram::1042...
Stop a currently active recording.
0 if the backend is the master and the recording belongs to a slave backend (seems like 0 will be returned even if there is a problem stopping the recording on the slave). If the recording is supposed to be on the connected backend, -1 is returned if the recording is not found. Otherwise, the recorder number will be returned where the recording was stopped.
