WD TV Live SMP lockmup

I have been downloading 20Gig movies and on occsion they lockm the system up and I have to reset. Files play fime on laptop. Is the reason the USB2 ports instead of USB3. Hard drives are all Western Digital USB2. Both are 2 TB.

No, more likely the reason is crappy files that software players might be able to compensate. It’s not about USB2 cause it can handle more bitrate than any Bluray.
