u see 19hd has a limit that maximum no. of HD CHANNELS will be 19 .....but if u take maximum HD channel pack available then changes happen in pack....like 199rs HD pack as chota pack or clubbed with ARP packages
HBO HITS HD , STAR WORLD PREMIERE HD and HBO DEFINDED HD are premium channels ....they have to be taken separately...not available in any pack....not even in MAGNUM pack
