Connected a hard drive with videos and it plays them fine.

Today's current dual-layer Blu-ray disc can only hold 50 gigabytes - as such, there is no official physical storage medium, other than a standard hard drive that can hold TRUE 4K-UHD feature length content, so don't confuse today's DVD's as anything that approaches what is possible.

I especially like the USB capabilities where I can put video recordings I shoot with my camera on a 2TB hard drive, USB them into this player and watch them on my TV (up-converted in resolution to at least 1080P I might add).

No issues using my Western Digital Passport USB Hard drive either

Super price and quality, 3-D, 4K ready, great picture, and available apps...

The 3-d works well and I dwelling access to streaming sires is very good.

It is 3-D capable, which is one of the first things I tried and was very impressed

then I guess there will be NOTHING to play 3-d Blu-rays as the studios seem to be abandoning us 3-d lovers

But BD-R and DVD-R work fine
