I found out in the end it is Sky customers that got the HD version of ZeeTV back, not Virgin media customers despite ZeeTV/Virgin media listing it as such.
Maybe Sky feel generous and give the HD stream or ability to VM customers one day, not going to hold my breath on it though.
Confirmed, good news just checked all in HD
I was wondering why it looked more clearer and sharper!
Thank you for reaching back out to us and for the update, glad to hear you are now able to watch a sharper clearer Zee TV via our newly added HD, enjoy, if you have any further issues/questions, please do not hesitate to reach back out.
