I had a hr34 and it had so many glitches. Dtv sent a tech out to look at it and he just said that they have lots of issues and he would just put in hr44 since its new and see if that fixes the issues. Just had it put in today so haven't tested it much but when I change channels I hear static and sometimes popping noises. Any idea what could cause this. I unhooked cables and reconnected but still does it. Was going to change out hdmi to see if that helps but its the first dvr I have had do this.
