Howto set stream buffer size in Amarok

[haimat]

Hi all,

I think the subject says it all -- how can I set (enlarge) the size of the buffer for internet streams in Amarok? I searched in settings window, but did not find anything useful. I only found that the input enging is xine -- do I have to set the buffer size for xine somehow?

Thanks in advance for any hint and/or idea!
Kind regards, Matthias
