It is not specific to HDMI or component...it's because of how long it takes to convert the video data to a picture on your hdtv screen vs how long it takes to convert the audio data to sound via your receiver. in general, switching between hdmi and component should not solve the problem...unfortunately. I think using a non-digital (red/white) cable from the HR20 to the receiver would maybe solve it, but then you don't have 5.1 or better sound to accompany the nice picture on the screen! just in the middle of growing pains of technology. to me it's the same as the fact that I can get the absolute best looking television picture for free over the air...but I need a antenna like from the 50s to get it and then I have to arrange it, re-arrange it, etc...to get the signal to come in. ironic, no?
