Created an attachment (id=35043)
non-copyrighted mpeg2 transport stream recorded by a settopbox
The previous attachment was sub-optimal. It shows is black image sequence but indeed is a non-decrypted content. Now I found a test channel with a nice test pattern (color stripes without any letters or logos). Therefore I submit a new attachment which is IMHO well-suited for inclusion into the source tree of shared-mime-info.
