Airtel Xstream has recently got the Chromecast button. PLease the cast button on the header.

Connect to a WiFi and press Cast

Casting feature does work on the Premium plan. OnlyTech was able to verify this through Airtel XStream STB, for which the XStream Premium subscription is free. However, not all content is available to Cast. For instance, we couldn’t cast the content from LionsGatePlay and were greeted with an error “This content is not eligible for casting”. Live TV content can’t use the feature as well, as that would be counterproductive to the Airtel’s DTH arm. The rest of the content from Hungama Play, ShemarooMe, Hoichoi, etc. worked fine though.
