hi again,

the high cpu load occurs if you have a large amount of timers.

the function Timers.SetEvents() (vdr.c line 580) is called every 5 seconds 
and parses through timers and channel schedules. i had some autotimers 
running within vdradmin and therefore a lot of timers in my timers.conf. 
seems like that was too much for my p2-350.

if you have the problem described above i'd recommend to disable autotimers 
and reduce the number of timers meanwhile.

bye, miko
