There appears to be
image quality issues. For best image quality, view HD wide screen programs where possible. If
HD content is not available view “Standard Definition” from a digital source.
Standard, analog TV will always be noticeably inferior to HD because your
digital flat panel TV has video that is many times better than old TV’s and
so you can see interference and deficiencies you did not know you had.
