I am going to get the Philips 30pw850h HD set and it doesn't have a DVI input on it, but I notice the 811 has DVI. Does this matter at all and will it affect my ability to get HD? Sorry if this seems like a silly question but I am new to HD and all I know is I want a HD set and enjoy the benefits of the broadcasts and just want to know the in's and out's before I get too involved.
