This is because, HD channels are priority see for example in your & my family one person is not that much familiar to this so much processing! And, we have subscribed to HD packs! Kya fayeda ese HD ka ki hmare ghar main koi dekhe hi ni! That's why frequently come to HD! Like if mom wants to watch Star Plus HD and before that Star Plus SD switches what will she do ?? 70% she doesn't recognize that weather it's HD or SD because, Gopi bahu is more important then HD!
