Thanks for the comments friends. To my knowledge i find some change in audio quality from airtel to videocon.
My audio setting is in dolby digital and i am getting symbol in the home theater also. But i think i have to watch all HD channels and observe sound quality.. I am totally happy with videocon. dth.
By the by what setting is required for audio delay ?
