i've got firefox set up to open multimedia files using vlc. likewise, my os (ubuntu studio 10.04) is set to do the same thing. however, i prefer to save multimedia files to my hard disk before opening them. i get the right prompt from firefox, and the file downloads fine. however, if i double-click the file in the firefox download manager it opens in movie player rather than vlc. why are these files opening in movie player? how can i get them to open in the proper application? i've gone through the preferences->applications->menu, and everything is set to either 'always ask' or 'vlc'; there are no entries for movie player. as i said above, these files are set in the os to open with vlc, and they do open correctly from an explorer (nautilus) window. a workaround is to right-click on the downloaded file in the download manager, open file location, find the file and open it properly, but it's a real pain and probably not intended behaviour. am i missing something completely? or is this a bug? edit: i now see below that the totem plugin is designed to handle audio and video streams, though streaming media isn't exactly the problem. i do have the vlc mozilla plugin installed, but it doesn't appear on the list below.
