Hi Kreplatch,
Just found your question as I have been unable to log on for a while.
You can see two folders, left and right, as I use a twin synchronised camera system, so I end up with files from the left and right cameras. If you have a 3d camera, such as the Fuji W3 or Sony Bloggie etc, the 3d video file from them will be in a single folder and will show as a single audio and stereo
