Comment 3 Myriam Schweingruber 2011-08-22 12:45:08 UTC 
Thank you for the feedback.

FWIW, you should avoid using the xine backend, as it is not maintained anymore. We currently recommend the vlc and the gstreamer backends.
Comment 4 Stefano Bianchi 2011-08-24 08:11:12 UTC 
The xine backend is apparently the default one in Fedora 14.
I switched to VLC to listen to ape files, which do not work with Xine and gstreamer. With VLC ape files work, but the reproduction of all music (including mp3, flac, etc.) is choppy, as if the files were corrupted. Switching again to xine or gstreamer solves this problem, but still no luck with ape files...
Comment 5 Myriam Schweingruber 2011-08-24 08:20:17 UTC 
IIRC Fedora 15 ships the phonon-backend-gstreamer as default now.
