My wife and I have decided to give up the high cost of DISH or DirecTV and try FTA. I purchased a used Mvidea FS-4000 with remote and have ordered an LNB for ku band. The receiver arrived today and I hooked it up to the old DirecTV dish and the receiver showed that a strong signal was being picked up but the scan shows nothing. I assume this is due to the LNB on the DirecTV dish. Some of the features and two slots in the front of the receiver leave us a bit confused. What we need is an owners installation manual that would have come with the receiver originally. I have spent hours Googling and have come up with many files on how to upgrade or patch but NO manual. Help!!
