Yesterday the installer hooked up my HR20. Was there for several hours and a few issues are still pending. Would appreciate anybody's help as I am experiencing some problems. Scenario:The installer hooked the HR20 to my 47" Philips HDTV. He ran the 2 satellite wires to the HR20 (there is some sort of adapter that that wires go into before going into the HR20). I also have a Hughes TIVO receiver in my other room (Non-HD). 1) For some reason when I switch channels – some channels don’t come and the message says (can’t remember the exact wording) “Searching for signal in Satellite tuner 2 (771)” and there is a blank screen. However other channels come fine. Then, some of the same channels are heavily pixilated – they freeze and you can’t even see the screen. This happens a lot on channels 70,71, etc and other regualr channels as well. Then at times the channels are fine. Weird thing was that my Hughes receiver in the other room (non-HD) was getting the same signal for the same satellite but was working fine. The installer changed the wiring, changed that adapter thingie but nothing worked. He said he is going to come tonight with a new receiver. My question was what is causing the problem. We tried to isolate it but couldn’t. Hopefully with the receiver change it does the trick. 2) Do all the HD Channels broadcast all programs in HD or is it the one’s that have “HD” next to them. For eg, I was watching channel 7 (WABC) which is in HD but some programs such as OPRAH didn’t have HD next to it. Same thing with CNNHD – is it always in HD or only some programs. Sometimes I just feel that the quality of the picture isn’t that amazing as I had thought. 3) Does HD quality depend on the signal strength. I get signal strength between 70-90 so that should be ok I guess. Only reason I ask is sometimes, for example, while watching a College Basketball game on ESPN that was in HD – it really wasn’t that great quality picture. Does getting a better HDMI cable make it better? 4) The Guide doesn’t even show programs after Feb 4th – is that normal? 5) The installer accidentally removed my old Direcv Dish instead of just adding the new HD dish and this basically screwed me over because with the old dish I was getting “International” channels. Now I can’t. When I called Cust svc they said that the installer could have put a bipolar connection. He will be coming tonight so I will tell him re-install the old dish as well. Hopefully he won’t charge me. I will probably have more questions but would appreciate your help in this. Thanks in advance!
