Though I was assured an HDMI capable box when upgrading our Charter cable service to HD, they were never able to produce one. An installer showed up with a component only box and tried to tell me that there is no difference between an HDMI and component connection to the tv. Fact is there is one big difference, HDMI is a true digital feed to the tv whereas component is a digital signal converted to analogue, then back to digital in the LCD tv's circuit. Some may not notice the quality hit from all of that transcoding, but I do and besides I was assured HDMI by their sales person, so just do it. I finally cancelled the upgrade after days of haggling with incompetent customer service reps who could only apologize then try to up-sell me on their "bundle" package. Yeah, right.
Charter is the worst cable provider I've come across, they make an excellent case for the dish.
