I just got digital cable through TimeWarner, using a Scientific Atlanta Explorer 8000 box. The features are great, but we expected a better picture. My tv is the Toshiba 50H82, widescreen & hidef. Would Avia or Video Essentials make a difference, or do you have to just settle for "this kind of picture" when using a big screen? I know that increasing size also increases artifacts or distortion or graininess, but do I have to give up quality for size? The Explorer 8000 literature says that in time they'll upgrade the software to process hidef, so I'd like to maintain this setup, if picture quality can improve while I wait.
