I'm musing about getting an DTV reciever so that I can access PBS's multicast streams, mess around a bit with HDTV, and so on. I live in Fairfax, VA, about 15 to 20 miles from most of the transmitters. I don't currently have an HD set. However, I do have a few good, high resolution computer monitors, so I'm thinking that any set top box would have to support VGA. Are there any good set top boxes available that support VGA monitors? I've only been able to find three such set top boxes around. Walmart has some kind of "US Digital" box, and Circuit City has a Motorola and a Samsung. I'm more inclined to go after the Samsung (a '451 model) because it has that RGB port.. Might some store in the local area carry more of a selection? I've been told (by an apologetic radio shack employee) that DirectTV is pressuring various retailers to de-emphasize their ATSC receivers... Comments?
