OK, let me vent some frustration....I've been messing with HT gear for over 35 years and I was beginning to think that I knew at least something about my hobby.....since I already have a Motorola 6412 with HDMI out, and a Philips plasma with HDMI in, my thinking was to buy the 2600, upgrade to a DVD player with HDMI, do the "2 cables in, 1 cable out" thing and be done with it! I think you guys are correct in that there is a potential problem with the "handshake" between the 2600 and the TV....sometimes(not always), when I switch to the HDMI input on the TV, I get a picture for a couple of seconds, then the screen alternates between flashing green and black....could this indicate a "handshake" problem? Can I have any confidence that this is a STB problem and not a defective 2600? Also, when I run auto setup, at the last screen where it tells you that the measurements were successful(p. 34 of the manual), it will not allow me to confirm the settings and "save them"....the GUI is slightly different at this point than what the manual shows.....thanks in advance for all the help....if you could shed a little more light on the potential "handshake" problem with the 6412 I would appreciate that also....once I get past this, I'll work on some of the other questions I've seen posted, like the "volume bar" not displaying on different inputs....Thanks, John
