Mmm... this is sort of fixed and sort of not.
I discovered that at the moment:
a) I cannot get Amarok to reproduce any audio in any way;
b) if I reproduce an mp3 the CPU goes 100% for a bunch of seconds (~10 secs)
and then goes to normal usage;
c) if I reproduce an ogg with the latest DirectShow oggfilter from:
http://downloads.xiph.org/releases/oggdsf/oggcodecs_0.81.15562-win32.exe
then CPU always stays 100% and it occupies a lot of memory;
d) if I reproduce an ogg with the oggcodecs 0.9.9.5 package in the repo then
Amarok crashes.

So, to sum up: the most of the problems are about ogg reproduction.
With the 0.9.9.5 codecs you get a crash; I think it's because they're old, this
page lists 0.9.9.6 as 2004:
http://www.free-codecs.com/download/Ogg_DirectShow_Filters.htm
With the 12/2008 Xiph codecs:
http://www.free-codecs.com/download/Filters_for_Ogg_Vorbis_Speex_Theora_and_FLAC.htm
http://www.xiph.org/dshow/
You get 100% CPU usage and high memory consumption.

So, afterall probably this is not Amarok's fault. Mp3 first seconds 100% CPU
usage somehow concerns me, that's why I won't close this report for now.

Some test with other Phonon backend maybe can shed some light on this kind of
issues, so please help me in this thread if you can:

Thanks.
