i connected my xbox crystal with a component cable minutes ago, and while the dashboard looks fine ( even though i can't enable the hd mode.. why)

if i try to run an emulator well it doesn't display anything other than noise, programs run but i cannot see them

what am i doing wrong? why the hd mode doesn't work at all?
this is the log
