Hi ,
according to my pesonal test, the easiest way to achieve what you wanna do is to creat on specific Favorite folder with
dedicated program such as Dreamboxedit , once done just add from BH menu the you would do to add a regular channel.
that is the same way when you want to add stream url, just create your stream then select the favorite folder where youwant it
to appear.
hope it will help you.
sincerly
