Hello everyone, I have DD free dish Mpeg2 set top box and Airtel SD box. I watch tv only for sports mainly cricket and news. As world cup is coming, I want to upgrade to HD box as I have hd tv. With DD sports Hd is launched should I upgrade to Mpeg 4 DD free dish box or Airtel Hd box? Both are available similar price of rs 900. I'm confused please help.
