Where does Media Encoder show drop or non-drop status of video?

I am working with a video with a burned-in timecode which shows as being non-drop frame.  However, my subtitling software reads the video as being drop-frame.  My guess is that the burnt-in timecode is incorrect and that the video actually is drop-frame.  However, I cannot find any way to check this theory of mine.  When I load the video in Media Encoder, it shows me that the frame rate is 29.97 -- But I already knew that. How can I find out if Media Encoder considers the video to be 29.97 drop frame or 29.97 non-drop frame?  I want to verify this so I can tell my client authoritatively that the burnt-in timecode is at odds with the actual timecode.  I can tell them that my subtitling software thinks the video is drop frame, but I'd like to have a second source to confirm that.
