chgu: this 100% mplayer-issue is definitely NOT happening here on my N800. I have KAGU running since 18 hours now (with 3 hours of real listening) without exiting the application, and battery is still fine (just lost one "LED" on the bar). looking at the cpu usage, I have 6% when kagu is not playing (mainly maemo_af_desktop using those 6%). when kagu is playing I see osso_media_server coming up, using just 2 cycles and 8% of total cpu usage. cheers, karl.
