Be carful, Directv is running alot of sites now and sueing alot of people. Directv is much easier to hack than Dishnet. Remember at this time only a hu card can be hacked for directv. The p4 hack is not availible yet. BLAnK WHITE SMARTCARDS WILL NOT WORK.anyone that says they will is lieing.Never plug a phoneline in with a hacked card.
The best loader i've found(reader/writer wont work for hu it must be a loader) is the omega2 from http://www.dss-tek.com. Yes you can get them for $50 less but you get what you pay for. Some wont load 4b cards.
