Have a irritating problem here. Occasionally (mbe once / twice a day I guess ) whilst wathcing Sky thru the PACE Sky+ decoder the sceeen gets the error message Sat Signal could not be found. Just before this message (very briefly) there is another message that I am unable to see. If I try to change channel here the system appears stuck for a while and then it allows me to change channel. If I then select another channel signal is restored and I can return to the previous channel I was watching ... all back to normal. Problem is sometimes this happes whilst recording and I do not know it has happened. Other than this system works very well indeed. If I could just cure this problem will be very happy. Briefly, system I am using to get dual sat feeds is a stacker/ de-stacker over one cable. Signal quality on both feeds are very high 4 out of 5 minimum. Signal Strenth both below half. I have also had to use a UHF blocker on one feed the stacker/destacker to work correctly. Any thots ? Rgds Steve.
