Samsung and other smart TVs have pretty terrible implementations of video players. The encoding is all over the map and no SmartTV to date will take the usual ISO file and play it correctly.

I gave up on the TV and now use an older laptop (2009 Sony Vaio to be exact) with the usual 2TB USB dirve and then play them from there. I added a Logitech K400 Plus for the control.

For the DVDs I used DVDFAB to make the ISOs and VLC Player plays these just like the real DVD player did.
