Short and sweet, more detail provided as needed: Is there any alternative to using the Comcast-issued HD cable box? One reason I'm interested is so that I don't have to pay the $10 a month extra (maybe), but moreover because I've found using the coaxial from the digital adapter gives me an awful picture on my TV. It's a Samsung UN26EH4000. When it's connected to the coaxial, I get a lot of ghosting and something else I don't know the technical term for; it's especially noticeable on words, such as on the channel pop-up, where a letter may have a trail of itself 5 times over, with each becoming progressively fainter. When connected to component, these issues largely disappear. So anyway, any details on this stuff and an HD cable box alternative are greatly appreciated (not as short and sweet as I thought)!
