Comcast DVR vs Directv HR20

Hi All-


I've had the Comcast Motorola 6412 (I think) DVR since it's release and while I've been relatively happy with the performance (minus the fact that I'm on my 3rd one) I can't stand how much I'm paying for their service.

I've recently caught wind of a special promotion through Directv HD DVR HR20-700+ AT9 Dish + 4 Month HD Prog.+ Install for $19.95.


Will I notice a difference in the picture quality?

Is the Comast HD picture better than Directv?

I've read that the HR20 doesn't have the local OTA HD working yet.


I don't necessarily mind the hastle of switching and I figure if I'm not satisfied I can always switch back and then get on another promo through Comcast.


Thanks for any advice!
