Hello All, Finally bit the bullet. Vip722 Top 250 and locals to be ihstalled next week. I am apprehensive about the upcoming installation. Presently I have a 508, Connected to a 32" lcd f/p tv. The 508 feeds an upstairs bedroom tv via rf/RG-6. It also is conneted with Svideo and RCA L/R audio, to a 17" lcd f/p monitor/tv tuner in the kitchen. This is a convience type install I did myself.......only 1 receiver so all tv's view the same programming. No DVD or VHS. I also have an ota roof antenna since I live in the NYC area and pull many PBS and local networks with very good pq. On my roof there is a DP Dish 500, and a DP Dish 300 interfaced with a DP34. The RG-6 down lead travels directly to the 508 in the living room. The system is properly grounded and has operated flawlessly since the first day I turned it on. Since I can not do the 722's install myself, I have not bothered to do too much resesrch for HD installations. So I have some questions that you may have answers for. I couldn't find a 722 manual to download, so I did visit E*'s tech portal and found it user unfriendly and cumbersum. Will E* supply an HDMI or component cables ? Wierless phone jack or anything I may have missed ? Can the existing dishes and cable routing described above be utilized for this installation ? 1- I would want my RG-6 downlead replaced with new 2500 mhz cable. Will the installer replace it ? 2-Do I need a new s/w to replace the DP34 ? 3-Is a diffrent lnb required ? 4- Will the installer connect my uhf roof antenna, [flat rubber roof] and should that also be cabled with 2500mhz RG-6 ? I think I read that 1 downlead with an adapter at the roof and also at the receiver will accomodate both dish and ota program information. Needless to say I am excited to be entering the world of HD, but because I am not able to do the install, I am a little, [ maybe a lot] Apprehensive ! Hope some replys will be forthcoming. Thank you all.
