Have just imported several MPG movies from my Sony HD camcorder into my NAS.
In this NAS, I have a share folder and 2 sub-folders, named Movies (movies downloaded from the Internet and are mainly .AVI) and this newly created Camcorder Movies (which are all .MPG)
In XBMC, I created a new source by pointing to this newly created subfolder. The other Movies subfolder I have been using to watch movies without any problems.
When I browse this Camcorder Movies subfolder on my iMac, I see all 154 MPG movies and I can watch then with VLC.
But on XBMC, when I select this source, it brings only one file which is not even seen on my iMac and when I try to exit using the Menu button in the remote, XBMC returns an error message with status 11.
