DirecTV == News Corp == BSkyB
DirecTV and BSkyB are both owned by News Corp (As is SkyItalia and Foxtel as well as a few others round the world), BSkyB does NOT participate in the North American market.
DirecTV was accused of leaking information on DishNetworks security keys to PayTV hackers (Dish would prob have done the same if Videoguard was crackable...it isn't, which is why DishNetwork gets hacked the most...they use Nagravision (heading to V3 which I've heard is either cracked or close to being cracked)
Videoguard has lasted as long as it has due to good security based on military style algorithms for cipher strength (NDS who wrote it and maintain it have done work for the Israeli Defence Forces and are based in Israel, also they are rumoured to be good friends with mossad (and to be honest would you make it know you had cracked Videoguard if you thought Mossad would come after you?....I wouldnt :-| )
Also Videoguard is customised for each provider (ie BskyB, Foxtel etc) meaning if one provider falls the others are secure still, plus I get the sense NDS have several versions already prepared in case of a major break in the coding (remember the big BSkyB card swap to the Dark blue viewing cards a few years back? rumours are that someone was very close to breaking that implementation of Videoguard so BSkyB swapped out all the cards and did an over the air box update to change the encryption and strengthen it.
(I keep an eye on what is going on as I find cryptographic cracking interesting....and plus watching the virtual games of cat and mouse is quite amusing as well as reading about someone getting too cocky and getting nicked - i.e. selling sat boxes pre-programmed with encrytion cracks (Heck a lot of local newspapers carry ads for Free To Air Satellite Boxes (especially in Canada) a euphemism for a box that is either re-programmed before sale or can be, by either the store or the customer themselves, cops aint stupid but selling Free To Air boxes is legal, reprogramming them isnt)
Anon....as I really dont want a visit from Mossad, and I really like being able to walk / breathe
