change boxkey in a genuine cam

[RR7]

Hi,

i have a valid subscription card that is locked to its decoder, i also have a genuine cam with an expired subscription card.

i wish to use the valid card in the cam, but this is blocked.

so i have two things i think i need to achieve.

1) extract the the boxkey+RSA from the valid card
2) reflash the cam with the same boxkey

the reason i want to use the cam is that i have a windows media center with fire-dtv and i wish to stream this tv around the house to my xbox 360 as well as the other benefits of windows media center.

i have a laptop with a pc card slot, it detects the device but obviously there is no driver for it.

which stuff do i need to get the boxkey? which program do i use to dump and reupload the cam firmware?

its a nagravision 3 cam and decoder/card, and i only need to use one of the devices at a time.

for messing around with a cam i'd reckon you'd need a cas programmer. but if the cam is nagra 3 and the card is aswell im not too sure how much support is out there for these.

are we talking virgin media nagra 3?

no its not virgin its cyfrowy polsat, DVB-S.

i was not aware virgin did cams, but i use polsat DVB-S and freeview DVB-T on my media centre.

not being able to use my cam means i lose all them nice features with DVB-S
