Scanning DVB and crash do not seem to be related. It seems to crash in DirectFB, somewhere related to fusion (ie. multi-application core). Could you try to recompile DirectFB in single application core, and do not load the fusion kernel module. PS : you may be better helped on the directfb-users mailing-list if it's really related to DirectFB... Rose M a ?crit : > Sorry my last mail is not quite good.
