hello my friend, the MTV's keys aren't public, i mean the keys for the MTV transponder on Astra19°E aren't public, if you use a metadream or dreamsoft and MTG10 you can watch some MTV's channels:
Mtv pulse, "11411/H/27500" hotbird 13°E
Gameone & Mtv france & VH1 & VH1 Polska & Mtv Polska,"11075/V/27500" hotbird 13°E
MTV base, "12303/V/27500" hotbird 13°E
MTV base, "11034/V/27500" hotbird 13°E
MTV pulse&MTV base france, "11387/H/27500" atlanticbird 12°W
that is all for the moment !
and be sure if there's any new key i will add theme immediately
