Just wondering if anyone else here has experienced the issue I am currently having. I have had the HR 20 for 11 months now and starting last Saturday night I noticed on many of my HD channels a strange grid of blue and white dots on screen, sometimes very faint but you can really see them on a dark background. It seems to show up on the HD locals, HD channels withing 202-362 range. The HD channels in the 70 channel range are find and HBO 501 is good, but the west coast offering of this channel has the same issues. All the SD channels are fine. I did have an ice storm and snow is coming down now in Chicago area. It seems that the MPEG2 Channels are ok,. but MPEG4 are being effected. My dish is way up on my roof so may have to get it looked at or re-alligned?
