Both are AAC, have the same basic properties (they sound the same) but Mediainfo reports one as being Italian!  It wasn't. But interestingly they have different delays relative to the video.

Perhaps TVOne is preparing for their DD5.1 stream by sending out two audio streams to start with and eventually replacing one of the AAC streams with a DD5.1 once they get their workflow sorted out.
