Hi JFR,
I have been doing some light testing with a code setup Jon created for me, to test all 256 commands. So far, I have been thru 3 sets of codes(I believe he has 6 or 7 sets to make up the 256) and I have found a service menu, test menu and 1 command that forces the HTL-HD's DVI connection into 720p mode. Unfortunately, I could not get it out of 720p mode and had to do a NVRam dump(via a previously found service menu), then have Directv(Pegasus) rehit my box to get my locals to show up again. At that point I packed it in for the night.
I will try again soon, but it probably won't be till after Christmas, as I have family coming in.
