The set top box problem?
Never think of that. But according to my satellite service provider, their set top box will only send out 576p picture if it is not connected using HDMI.
And I've already have this problem even before our HD set top box being install and the old set top box were connected using s-video during that time.
And worst, i've sold off my component cable since I ditch my DVD player (ouch!), and only have those audio cable with me (still have the Emotiva ultra series RCA cable), can I use those?

I've sent the SR6003 to update the firmware just 2 weeks back to solve the problem, however, even after update, it didn't help... \:\(
