Thanks. I found I can only play simple format .ram file which only contains Url link like rtsp or http. If the format is very complicated, I can't play with Mplayer. I can use RealPlayer to click real movie picture on http://realplayer.com to play movie, but I can't use Mplayer even I past the content to the back of "mplayer -playlist" command. Another thing, the system seems to consider .rm & .ram as same kind of file. How can I double click .rm to launch "mplayer" command and double click .ram to launch "mplayer -playlist" command? I tried use gnome-file-types-properties, it doesn't work. Any ideas?
