Hi People I have been looking into two Panasonic recorders. The DMR-EX85EB-S and the DMR-EX75EB-S. The only difference that I can see between the two is that the EX85 has a 250gb hard disc and the EX75 has a 160gb. Does anyone know if this is the only difference or is there something else that I've not noticed. Also are either of these players good at HDMI upscaling, compared to a stand alone player worth around £200???
