I have a viewsat platinum and pick up on echostar 6.8 and 7. I erased all the channels and rescanned and lost the majority of them. Then I downloaded a new program file (Platinum-061220P.PGM) and ereased and re-scanned. I keep losing more and more channels. I read a post about turning one of the LNB's off on one satellite while you scan the other. That didn't work out too well. If there is anyone that can help me out it would be appreciated.
