WDTV Live streaming Gen3 Crashing

Did exactly what was suggested and moved the unit from inside the entertainment center to the top where there is plenty of airflow. Worked great for about 2.5hrs, then crashed. The box wasn’t as hot as when it was inside the cabinet, but it was a little warm. Is this a hardware problem, and is WD working on a solution? I would hate to go thru all the hoops to get it replaced via the warranty only to have the same problem with the replacement unit.

Please let me know.

Thank you
