its going to be very difficult your box is pretty much a FTA box and very old and limited [ SD Only ] .
There is not very much you will still be able to watch on it since many channels already moved to HD [ High Definition ]
you should be able to open some SD Biss feeds in 4:2:0 format
The BISS Menu can be accessed (when you are on any BISS encrypted TV/Radio channel) by pressing 8-2-8-0 on the remote control , IF FEED IS IN HD OR 4:2:2 Then you will hear Audio only not Video pictures as your box wont work with 4:2:2 format feeds or even any feeds that are HD
my suggestion is get rid of this old inferior box
upgrade to a HD Box for Example TM5402 M3 HD
That is if You have any desire whatsoever to actually watch any scrambled channels [ Majority of which are in HD only as mentioned ]
Good luck : )
