I lost HD channels while upgrading from SOUTH JUMBO FAMILY to FAMILY SPORTS. I even lost the 1 free regional pack (Kannada).
Then I had to call CC to reactivate HD and that 1 free regional pack.
So I think if I downgrade/upgrade again, I will loose all these and have to call CC again to reactivate.
By the one more query, whether Kushi Pack(Karnataka) allows selection of FULL ON HD with it?
