Hi I have a 4DTV receiver with a 10 ft Winguard mesh dish for c/ku band, that was installed in 1993. I used to get all the NFL preseason games (especially the Packers), but each year it is getting harder. I don't use the dish for programming anymore, as I have Direct TV and get the NFL Sunday ticket. I've read in a forum that the Packers are broadcasted in HD and I would need a HD receiver. Quali-Tv and AZBOX were mentioned. Do these receivers replace the 4DTV receiver or are both needed for proper operation? If these receivers replace the 4DTV receiver, would I have to reprogram the satellites in or do I use the 4DTV receiver to move the dish to the desired satellites? Are a lot of the HD programs on one satellite? Is there anything else I would need to buy to received the Packer games again. Are the LNB's I have for c/ku band ok for hd reception? I replaced them about a year ago, as my house was struct by lightening. Sorry for all the questions, as this is all new to me again. Your help would be greatly appreciated.
