Its not a good solution because when you add a new channel in favorites, it goes to the last place. For example, I have favorite channels 900 to 930, all the movie channels are 910 to 918. If TS adds a new movie channel and I add it into my favorites list, it will become fav channel no. 931. But I wanted it to be 919, so I will have to deselect all favorite channels and then re-select all favorites one by one.
In videocon d2h, all HD channels begin from no. 900 and are already sorted category wise. I don't know why TS does not follow this.
