I know this thread has been going for quite a while! I am still using my 5296D and am trying to connect it to an antenna to pick up the local DTV stations. It won't seem to find any DTV stations on either Air or Cable connections. I know it has an ATSC tuner so it should! I am wondering if the firmware mentioned in this post would help at all. The links are dead, but does anyone still have it that they can email it to me??
Any help would be really appreciated. I would hate to have to buy a new HDTV to save money by using an antenna. . . the irony.
