The HD Box works fine. Plug it in, activate it through Direct TV... and it works. My disappointment is in the shady business practices of Direct TV. You are not BUYING this receiver, although the product description would imply that you are. According to the customer service agent I just spoke with, you are not able to BUY any receiver through any retail outlet - they are all sold as "leased products." As noted in the fine print (supposably), Direct TV only leases their boxes. As soon as you activate the box through Direct TV, it's theirs. You will be charged a $5 monthly "leased receiver" fee, despite the fact that you "purchased" the box from a retail outlet. If you do not return the box, to them, when you're done with their service, they will charge you a hefty fee for keeping the box. (The box you paid for through a different retail store.) Also, you are required to extend your contract, with Direct TV, for two years when you add or upgrade equiptment. If you cancel before the 2 years is up, you're hit with another hefty "early termination" fee. Even if you are to "borrow" a receiver from someone else, you must pay for a new access card (so it can be linked to your account) and they will still charge you a $5 monthly fee, although they call the fee a programming access fee, rather than a leased receiver fee. Rediculous! Buyer, beware!
We were upgrading our equiptment to receive HD programming. We were not notified there would be a $5 lease fee, up front. We were not notified our contract would be extended if we upgraded our equiptment, until we called to inquire about why there was a "leased receiver" fee on our bill. I am really disappointed in the manipulative business practices of Direct TV, at this point. I guarantee I will never "renew my contract" with this company, again.
