I have read just enough to be confused. My question is this: in setting up a home theater, is there a big difference between component video hookup and HDMI? My understanding (probably flawed) is that component and HDMI are very similar, with HDMI just having both digital audio and video on one cable. Reflecting on the the first question, can someone tell the difference between a video signal hooked up with HDMI and one with component video in terms of both a DirecTV receiver and a progressive scan DVD player. Thanks.
