can't watch season episodes without starting at the beginning

What series?  Most OD series let you choose from "Browse Episodes in Series".

Sorry....you said online. 

Hey skeeterintexas- I'm slingboxing it thru roku but even in on demand they only have 2 seasons 4 shows. history channel curse of oak island

On Demand can be a strange animal.  Not every series has every episode available. 

I don't if it's a Uverse thing or a network thing or maybe a series thing.

Well guess I got my answer, now on demand is completely down. "Try back later" it says. Thanks for the reply
