Why is it that a plugin/embedded player that works in Firefox does not work in Konqueror.
Dunno, works fine over here.
Perhaps it depends om the website you are visiting.
Secondly, in konqueror itself, how do I configure playing of streaming media. I mean I know of Settings --> Configure Konqueror --> File Associations and have tried endlessly to install every player and tell konqueror about it but nothing seems to work. Is there a tutorial that can help me with this?
I think you should edit/remove the protocol handler for kaffeine.
