+.I WARNING:
+The way MPlayer parses and uses playlist files is not safe against
+maliciously constructed files.
+Such files may trigger harmful actions.
+This has been the case for all MPlayer versions, but unfortunately this
+fact was not well documented earlier, and some people have even misguidedly
+recommended use of -playlist with untrusted sources.
+Do NOT use -playlist with random internet sources or files you don't trust!

 This option is considered an entry so options found after it will apply
