well, I didn't purchase recalbox, but I wanna know if it can help my problem, if it is yes, i would like to buy it, my Samsung 55" Smart TV will not play two MP4 files I have on a WD HDD (Plugged into the USB Port). Both files display "The selected file is not currently supported". I searched at http://www.videoconverterfactory.com/tips/samsung-tv-mp4.html. and https://community.netgear.com/t5/Stora-Legacy/Why-can-t-I-watch-mp4-files-on-my-TVs/td-p/434351 but they all failed by some unknown reasons, so I really wanna know recalbox can help me or not???Please
