Making SMPlayer the default player
 

I am currently using Xubuntu and I would like to know if there is a way to make SMPlayer my default multi-media player? I've searched through the application itself but I don't see anything that suggests how to do that. Is it possible? Thanks in advance.

there should be on the properties of the .avi,.wmv,.ogg,.asf,... files a "open with" option

Yes, I can exercise those options manually, but I'm wanting to know if there is a setting that will utilize SMPlayer by default? It would seem that it should be possible to do this; I just can't figure out how.

Xfce 4.10 should have some MIME type editor, look into that.

The "Open with ..." item should have a check box saying something like "use this for all files of this type". You can set the file association to what you want either in your File Manager or in the settings for your desktop.

I still haven't figured out a way to establish SMPlayer as the default media player on Xubuntu. I'm sure it can't be that difficult...can it? Shouldn't there be a simple command, or a terminal string that sets SMPlayer in place? The media player that is packaged with Xubuntu is junk!

What Xubuntu version do you use?

Still struggling with this. The "Open with" item referred to above does have a "use this for all files of this type" option,
but it is a dead box. I cannot write anything in it. The default player is gmusicbrowser and it always reverts to that. I'm sure there must be a way to do this; I just haven't figured it out. I have mplayer and smplayer loaded but the trick is how to get a stream site to recognize it.

I think I have Xubuntu 12.04, but I have installed all the upgrades on a regular basis. What I have is up to date.
