Well Bing+ and xtream boxes r specially made for Related DTH users...Both have their own software on those devices...dth ops have full control of the devices...I think xtream boxes r locked or not working without DTH subscription...tatasky too may do this in future...Users who want OTT services in their DTH box can only better to opt for them... It's not for OTT only users...They can opt for any other Android boxes...
It's not fair to compare DTH Android boxes with OTT only boxes....
