CBS On Demand

While watching shows via CBS On Demand, we will get part way through the show, and then get 'kicked out' of the show and back to whatever channel we were watching before we started watching the on demand show. We're not able to fast forward to the point that we were kicked out, and if we start the show over again, we get to the same point in the show and get kicked out again. No idea why this is happening and would very much like to solve this issue.
