Hooray! My HD H-20-100 finally got the "software upgrade" last night. Now I can finally use the HDMI that has been "incompatible" with my Samsung 42 inch DLP the past 10 months. Could someone please advise/recommend how to set up the receiver. Native on or off, check 480, 720, and 1080 or uncheck 420 and let TV upconvert to 720 or 1080. I have ready many suggestions on other threads and am not sure what is best. Any help is appreciated. Anxious to see if HDMI is noticeably different than the component I have used for nearly the last year! Thanks.
