When you connect a DVD/Blu Ray Player to a TV via an A/V amp using HDMI leads is it possible to switch off any upscaling properties the the amp possesses and let the player do its own thing? I haven't got a specific amp in mind as yet but I was wondering wether that option is standard on all amps that upscale or wether I would need to buy an amp that was capable of bypassing that option, or alternatively connect the amp via different cable and just HDMI the player straight to the TV??
