I have tried twice over a few days and got the same result.
If I access the screen that shows all the tuners in use and choose one of the progress that is being recorded, I am given the options of "stop", "join live" or "start from beginning"...and the "start from beginning" option does nothing.
To accomplish the goal of watching the program from the beginning I have to navigate to the DVR menu and find the program tile and "start from beginning" works from there.
