I am having some problems with my toshiba DT-3000 receiver. A bunch of my channels keep breaking up ESPN, ESPNHD, some music channels, half of the NFL HD games. Here's the thing in my bedroom upstairs I have a Directv tivo unit. No issues at all with the signal. I have been on the roof and calibrated the dish to my heart's content. I am now thinking that maybe the length of cable is affecting my signal. I never had this problem before, and now all of a sudden in the last two months I am getting low signal on the Toshiba. I have lived at my house for over 3 years. I bought one of the inline amps to see if this wil solve the problem, but I haven't installed it yet because I have not received it in the mail yet. If this doesn't work does anyone know of a reputable outfit that I can call in Portland, Oregon to fix this. Directv wants to charge me $70 for a house call and I want to see if I can deal with a local installer. Any thought would be appreciated
