DISEqC 1.2 & usals question

[shultz]

Last night i was flippin through the sats from 30w to 129w and everything was ok. today i flip through and when i get on a circular sat, the dish takes off to the east! (example: i'm watching gnf movies on 97w, and i go to 110w. instead of going west to 110w, it heads east) i have 2 lnbs (universal & dss) side-by-side. the uni's are on usals, the dss are on 1.2 (so i can move the dish to that sat) i had it all setup and was working fine till this morning. i didn't mess with ANY settings last night, so what happened? right now i recalculated the dss sats and have them back again and everything is back to normal, but i can't figure out what and why that happened. anybody got any ideas?
