I will switch my garbage Comcast service (Enough with them too expensive and you get nothing ) to DishNetwotk end of September (Waiting bcs I bought the MLB package with Comcast). I have a 4 TV sets 2 HD 2 STD. are they going to use Comcast wiring or they will do rewiring around the house (If they do, how is the job they usually do for that). Should I get 622 receiver paying $200 (I'm not crazy about recording and pausing etc stuff.) is there a difference between picture quality with 622 receiver or free HD receiver they provide if I don't choose to get 622. Please advice me what to look for anything I should have or not to have.
