Hello, I am new to this forum - found it by searching for info on some problems I am having with my HR-21 700 receiver. I get some of the HD channels, but not all - notably absent are the sports HD ones, like YES, ESPN etc. The lower ones, like 70, 71 etc. seem to work. I don't know if this is a new problem or not - I didn't notice it until baseball season. The receiver was installed in Jan. and of course, Directv said they'll come out and check it out for $80 service call, because I am out of warranty. I have called several times, and re-set etc. Today, I notice that there is a lot of grey ghosting when I try to change channels. I am so fed up that I am ready to dump them, but know that my alternative, Charter cable, is no picnic either. Anybody else having any problems like this? Thanks in advance!
