I am trying to search other threads but it is difficult. I hace four Series 1 DirecTV Tivo units with a lifetime Tivo subscription. Two of the units have been modified to have 80-100 GB drives. I ordered a Pioneer 50" Plasma TV and got a great deal on a HR10-250 HD Tivo unit. The installer was out yesterday and spent 10 minutes and said that there was no line of site for the 3 LNB upgrade dish and he left. I think that there would be a good place to put it on the corner of my property instead of the roof. I called DirecTV and the person I spoke with said that if the installer said there was no clear line of site - that was it. Has anyone been able to recover from that? I called Comcast Cable and they have a reasonable deal where I can get $25 off per month for 16 months and DVR's rent for 9.99 per month. Does anyone have any advice or anything good to say about Comcast or their DVR's. My entire family loves Tivo and they are not happy that we have to switch. I understand that Comcast might have a Tivo solution sometime this year. Can I sell my lifetime DirecTV tivo subscription and four DirecTV boxes? Has anyone else done that? Also will my DirecTV Tivo units continue to play the recorded material after my DirecTV account is closed. Thanks for any info.
