I used to have 1 account and move boxes between locations as we traveled between houses.. however I never called DTV and told them ... never was an issue.. however we upgraded our sat at our primary house and it was several months until we took boxes to the other house again (its at the lake).. so our normal house is HD.. we have an HD box and some regular boxes with filters on them.. Now we tried the regular box (like we always did) at the lake using the same normal sat we always had.. but it won't work.. is that b/c we now need an HD sat dish at the lake (just like at the normal house) and a filter on the regular box.. or do we just need filters on the regular box??? thanks in advance.
