Hello Ville, I'm making this a ML posting to allow others to comment on this, too. Hope that's ok with you. Well, looking at <pthread.h> it does look like there actually should be a pointer to a 'struct sched_param'. But then again it says: The realtime scheduling policies SCHED_RR and SCHED_FIFO are available only to processes with superuser privileges. which VDR usually isn't. Since I assume that the line in question doesn't have any effect if a NULL pointer is given as 'param', maybe it's safe to drop it altogether? Klaus
