I had to do full revamp of favs now. I have to repeat this in my parents set top box too. I won't be there for another 2 weeks. They'll miss some TV channels now.
If they are changing LCN they should have relocate the fav channel frequency in fav LCN too.
Like if Vijay Super is on 900 in fav and now LCN change then make the same channel on 900 LCN in fav.
See, u ask set favourite option from 0 to 99 instead of 900 to 949. And also put condition, if they change LCN, it will not affect the favourite option. This all facility available in Arasu Cable TV setup box.
