Is it possible to have stereo sound from an external mic on a Canon Vixia HF G20 I have a Canon Vixia HF G20 and I cannot find anywhere in the manual about an external mic in stereo mode. The "advanced hot shoe" does support stereo and surround sound but through the Line In/Mic port on the camera I can't seem to produce stereo sound. My source is definitely stereo. Any suggestions?
According to the Using Commercially Available Microphones section on page 76 of the manual for the HF G20, it should be possible to connect a stereo microphone to the external mic connection.  There may be some problem with the kind of a source you are using or the way you are connecting it.
