You will need a Slimline AU9-SL3 dish with a SL3 LNB, if you want to keep the international programming from 95W, you will need to keep your World Direct dish and run a cable from it to your multi switch, you will just use the cable that is hooked up to the linear LNB that is on the right hand side (I believe) if you are facing the dish. You can use any HR reciever if you want a HD-DVR with the exception of the HR34 (it is SWM only, unelss you want to upgrade to a SWM mulitiswitch) and any H series HD receiver, except for the H25, which again is SWM only. If you do not do SWM you will need to use B-Band converters with all of the receivers/dvrs (that are HD) except if you get a HR23 or H23. Probably the cheapest route for you to go is to call DirecTV and see about an upgrade. You are looking at about $100 for the dish and about $100 for a HD receiver or $200 for a HD DVR (that is the lease price, you would be under a 2 year commitment).
