Although the station sorting may be cumbersome, but is anyway necessary only once. For this you can create multiple channel lists according to their own discretion.
For the premiere DRS5005 requires a Nagravision card, no NDS.
The only complaint on my part: the teletext signal is not looped through to the TV, Teletext can therefore only be accessed with the (slower) application of the receiver. But unfortunately This silenced the TV sound, except for display of teletext in the TV picture.
