I added the *.rm type as you instructed but it didn't work. When I try to play a .rm file in Amarok, it gives the following two error messages:
Eror Loading Media
There is no available decoder.
A problem occured while loading a library or decoder.
xine parameters: cook.so
In the file associations, other than the vnd.rn-realaudio
type, there is also a type called x-real-audio
which is associated with Movie Player and Real Player and has the same extensions as vnd.rn-realaudio
. I added Amarok to this list as well but no luck.
I guess it has to do with some plugin. May be I will have to register the plugin responsible for playing real audio files in Amarok. Any ideas?
