I currently am using an HR34. My understanding is that to show only HD channels in the guide, you have to press Guide twice, then the down arrow 7 times until you get to "HDTV Channels." Is there a better way that doesn't require 9 button presses? I supposed I could create a favorites list with only HD channels, but that would be tedious. If that's the only method, I'll do it. Just curious if there is a better way.
