FYI - This will not help your particular situation based on how you are viewing but I do not use Tablo for live tv at home. After I removed the dish network( 
) I split the antenna connections, one going into tablo and the other to the house coax. Then I fed all the coax to the tv.
This helps me wtih
1) Watching live tv it does not take a long time(buffering)
2) I can switch between channels easily and
3) It does not take a tv turner from the tablo so it can still record 4 shows when I am watching even two live tvs in two rooms
