Here's the situation... I'm helping my brother out (long distance--he's in another state) with his Hughes HDVR2 DirecTV/TIVO receiver. He installed a Phase III dish and has two RG6 cables running from it to the HDVR2 (hereafter I'll just call it the TIVO). He gets a strong signal strength when going through the guided sat. setup on all three birds and both ln1 and ln2--that is, both ln1 and ln2's bar graphs show a strong signal (he properly chose the oval dish, 2 cables. He contines with the guided setup to finish it, but when the guided sat. setup is near completion, it tells him this: Now, when he presses "live TV" on the remote to watch something, he can get a picture on most channels. In fact, he was able to get ch. 206 on one tuner and ch. 514 on the other tuner. However, if he turned to channel 212, 231, 307, 309, 604, 380, 382, 386, 388, or several other specific channels, for example, he got the message "searching for satellite signal on sat. ln2" and no subsequent picture. If one of the tuners were bad, I'm assuming that he wouldn't be able to get ANY picture on one, and thus would not have been able to view ch. 514 and ch. 206 separately. Note: When he goes to his setup menu and chooses a simple "test signal" request, he can get in the mid-90's on ALL three satellites--101, 119, and 110--and on both ln1 and ln2. Neither he nor I have ever experienced this problem before, so we're baffled as to what the cause of this can be. Can anyone hazard a guess as to what to do here? Thanks.
