I thought it was just random - but has happened again and again last few days. Seems a systemic error. When goes to a commercial set and returns - it is in a random point in the show and not where it left off.
Example is The Voice recent episode. Also happened with two Fox Shows.
When you return from a commercial break point it has "rewound" to the prior break point in the show and repeats. Another form of commercial loops - as now to get back to where it should be in the show - you have to watch commercials yet again. You have to manual move around and manage because every time it goes to a commercial set (dot on timeline) when it returns it can be anywhere in timeline and you have to manual move to the point it really should be....
