Someone here brought up that dish might really sending 1080i/60 and since your set can accept 1080p/24 & 60 it just reports 1080p, while most sets report 1080i.
Don't be sorry. Please just share your secret config with everyone else here.
I have the exact same tv and mine reports 1080i. downloaded the beast several times and all the episodes and it is always 1080i for me.
