I'm a long-term subsciber to Direct TV and have recently installed an RPTV. I am pleased with the Direct TV standard signal quality on my new Sony 51ws510. However, I want to upgrade to HDTV and add at least one more receiver, and as you know if your an existing subscriber nothing comes free. Dish Network is offering a free-install 3 receiver package that includes an HDTV receiver. However, before I make the switch I have a couple of questions: 1. Anyone have any experience with signal quality and general service between these providers? Even though I'd be going to HDTV, I know most of the channels will be standard, and want to at least equal Direct TV quality. 2. How many Hi-Definition channels does Dish offer? 3. Dish is offering either a free DVR or HDTV Receiver with their install package. If I opt for the HDTV can I add a DVR independent of Dish, or will I have to pay Dish for adding it?
