Not exactly sure what you are asking, digital adapter to what? There are many "digital adapters". You don't need dvr to use the TV, that's only for recording.

What I mean is: will the signal coming from the digital adapter give me as good a picture as the signal from a hd top-set box? I do not want to degrade the picture quality that I currently get from having the hd-dvr top-set box.
