I currently have TiVO and DISH 6000. I am considering the 921 in order to record HDTV, but am concerned that the DISH DVR wil leave me regretting the loss of TiVO (no season passes in particular). Anyone have experience with both that can offer an opinion? Is there any way to get the equivalent of a season pass by programming the DISH DVR? Can you set DISH DVR to record same time every week? Thanks.
