I didn't face any issue with the telecast till now. Although i found MTV HD picture quality better than that of Sports 18 HD on Tata Play atleast.
They have put on a good panel for English broadcast and we should applaud them for the efforts they are putting in.
For Jio Cinema app, i never liked the UI, quality provided by the app even earlier also. They should have worked on the app first, before telecasting world cup matches on this platform. I believe they will learn and improve.
