On my mother & father's HR20-100, the top of the guide on the left side is black and the fonts that do appear do not appear correctly. The PIP appears correctly and all shows appear correct. Also, during the reboot, the progress bar has the same issue. I've tried rebooting, then a 0-2-4-6-8 reboot, and I reset the box to defaults. I also tried disconnecting the HDMI cable and reconnecting it, but the problem still appears. The channels in the guide appear correctly, and the info banner appear correctly as well. What I haven't tried because of time available is yet is a complete rebuild because it would wipe the hard drive completely, or switching cables to component. They have a 50 inch Vizio Plasma TV connected by an HDMI cable to the HR20. Any ideas???
