Scanning problems for 91

[styzer]

I have a nano premium receiver and works fine with dn but I am having a problem scanning channels on nim 91. Only 140 channels showing up. Now I checked all my settings and they are correct. I hooked up my old viewsat ultra and did a scan and got all the channels showing up. So my dish hasn't moved. I was thinking of getting a north sub. to go with my other sub for south but if I can't load all the channels I guess I won't be doing that. Anyone have any ideas what could fix this?

When you scan all the channels you are probably just getting the vertical or horizontal transponders!
Is that your problem?

I am getting some horizontal and some vertical. Don't know why I am not getting all though?
