Tvheadend

Hello, I am new to the forum, but I need a help already read enough already searched enough moms nothing specific, my problem and his solution and for academic purposes, I have a TBS6985 card connected to tvheadend, capturing several channels, a satellite, using newcand to unblock the channels, but when I put the CS, has several flaws, I can put ten CS but the channel never stops showing errors, the picture freezes, the channel falls and back, I need each CS to be directed to a channel, a CS a channel, and so on, but I did not find anything on tvheadend that can do that, thanks who understands can help, below I will put the images of the problem.
