My 1st post here so here it goes

I have Humax Naci 5700 with a mosc from tv k*K* (4801) pointing to Hispasat.
I can see abt 80% of the provider but some channels do not open, even if they're in the same transponder.
For example I can not see: MTV hits, MTV base, Discover Channel, Sport TV2, Fox, Rai Uno, Arte...etc, etc..
I know the card is rom 10 because the guy who sold it to me told me so.
My question is: Do I have any chance with this card to see ALL the Channels ?! And what abt the Spanish provider (D+) ?

Any help would be higly appreciated
