No, that's not why I wanted it. I've got two DTivo units, one with a bigger HD and one stock. Both have problems recording anything on ABC. However, if you switch to ABC, you can watch it just fine. They recently added locals, and that had to be done via a 2nd dish. The last time I checked the signal strength was great.
I'm looking ahead a little in anticipation of Tivo putting commercials in while fast forwarding, etc. as well as fixing this issue.
