i couldn't find a topic about my problem: playback of mp3 give a lot of stuttering. sometimes more, sometimes a little less/shorter interrupts. the problem is NOT hissing sound or something like that. it stutters.
stuttering appears several times during one song, and always only for a fracture of a second. but you can clearly notice it - even my wife does. it's just not possible to hear to music.
it doesn't change with itunes, vlc, mplayer ...
os is 10.5.7, bios A05, 2gig RAM, low temp (just after starting the dell - so no heat issue), no other apps running
any ideas welcome
