This Sunday matches not live on star utsav movies because star utsav movies busy with "bhul bhulaiya" at 7PM.
16 April matches also not available because star utsav movies showing "samrat prithiviraj" at 7PM.
I think, Star Utsav Movies using Star Sports feed today. Because, they are using english narration of sponsor brands with star on the background.
Edit - Now, they are showing graphics of Star Gold/Utsav Movies.
Looks like all CSK matches will live on star utsav movies
First 31st March
Second 3rd April
And now third csk match also live on star utsav movies
Hope they show some rajasthan matches also.
