Rbyers, I feel that when a product like this is being considered for purchase, one should use the product to it's full potential as it was so intended. Current LCD flat panels IMHO are designed and advertised specifically as being able to display the current gold standard, 1080i. Their backward compatible with SD is secondary. I know when I decided to make my purchase I would not settle for anything less than viewing from the best quality signal available, Cox 1080i. SD in my area, which is South Orange County, is available with Cox basic service. However for $5 extra a month for the rental of their HD box. The same channels 2,3,4,5,7,11 are offered in HD. KOCE, TNT INHD, INHD2 are also included. For an additional $5 they add ESPN HD and DiscoveryHD. Seems pretty reasonable to me!!! Just my humble opinion.
