Maybe doordarshan stopped DD Sports 1.0 feed on C band and now directly uplinking same on DD Free Dish Ku band transponder hence Airtel Digital TV stopped receiving it from yesterday night. Good step taken so as to protect interest of private sports broadcasters which hold rights of various sports events which get aired on DD Sports 1.0 and are sometimes this feed is made available on private pay tv platforms which should not happen & not allowed as per rules
