The same was done with HBO HD and Sony BBC Earth HD. Since Videocon didn't have them, Dish TV removed them.
But now they are removing a channel that is present on both DTHs.
In fact, in the early days of TravelXP HD (fom 2011 onwards), these two were the only DTHs to carry the channel. TS added it in 2016 and Sun in 2017/18. Airtel still doesn't have it. This was such a long-standing channel on Dish-d2h. Shame on Dish-d2h for trying to remove HD channels until they reach Independent TV.
