This message is a bit misleading. It can mean that there is something wrong with the file. I got sent a file just recently from another user that showed a samplerate of 0, 0 kbps and also 0 channels and the only player that could play it somehow was Quicktime (even there no seek was possible). All other players refused to play that file.
So if you see this message, please double check that the file is OK.
