The best way to find out is to call the Samsung customer service center in your region. Unfortunately, I can only speak on U.S. products.
That said, the U.S. version can use either a USB pen drive, and some users have reported some successes with hard-drives, although not all USB drives will work.
just a quick question.
Could you please let me know if with Samsumg UE40B6000VW is possible to look at the movies using an USB pen or if a multimedia hard disk is needed.
