my buddy recently spend $2000 on a plasma (good deal), but realized the same problem you have. in order to recieve HD signal rom directv, you must 1st have a HD dish. most likely your older dish only has one reciever while an HD dish has three. whether your built in HD reciever is compatible with directv is something you have to ask them. the HD/digital box will have three inputs to your HDTV instead of the one you probably have now. needless to say, all this from directv will cost you more and you still wont get the local HD broadcast unless you set an antenna along with the new dish. if you have COMCAST in your area, they have a basic package (4 HD channels, 4 local HD) for $50 per month.
Hi, We have just purchased a Sony LCD KDF50WE655 with a built in HD receiver.....we have Direct TV currently, but its kinda old, we've had it for about 7 years. I know I must seem dumb, but I can't figure this stuff out......somewhere I read we might need a new Direct TV dish to receive HD programming?? Also, because our HD receiver is built in do we need an additional one from Direct TV.......I'm confused....also we'd like to add TiVo....does this mean we'd have to add two recievers???? HELP?????????? Thanks in advance, Pat
