Hi guys,
I need a little help form all airtel digital tv users who are using HD connection.
I don't have a HDTV yet but i am planning to upgrade to HD set top box. I know that HD channels have better qaulity. Is the picture quality and sound quality for SD channels also improve when watched through HD box?
