I'm about to take the plunge and purchase a 61" Samsung DLP RPTV Model HLN617W. This is at the upper end of my budget for a TV, but I currently have a 7 year-old Toshiba CF36G40 (36" 4:3 CRT), so it's time for an upgrade. I've heard good reviews both regarding the "HD2" technology and this particular model. I'm aware of potentially seeing "rainbows" so I'll inspect one before purchasing and will purchase it at a place that has money-back guarantee. Here's my issue: I currently do not have access to HDTV. I own a Dish Network DVR 721 on which I recieve standard def. programming. I know Dish Network offers HDTV receivers, but I'm attached to the DVR. I'm not yet ready to upgrade to their 9xx series DVR which offers HD recording capability. Therefore all of my viewing will consist of SD programming via Dish Network (except of course 420p DVD). Many of the reviews state that "poor signals" viewed with this Samsung look "exceptionally poor". I don't know if the "poor signals" to which the reviewers are referring envelope all SDTV, or just over-the-air weak signals. I guess what I'm tring to ask is, "Will this upgrade look like a downgrade if I only use it for SDTV & occasional progressive scan DVD?" Thanks for advising a noobie.
