"I can't open .mov files on my Samsung TV, it showed that "This file format is not supported yet". What can I do? I really wanna play these MOV videos on Samsung TV. Thank you for any tip!"
MOV stands for apple QuickTime movie, common multimedia compressing method developed by apple. Currently, Samsung's connect share feature, which is developed for playing videos on Samsung TV through USB external drive doesn't support playback of MOV. If you wanna watch MOV movies on Samsung TV, then you'd better transcode MOV to MP4 in H.264/MPEG-4 AVC video codec, which is clearly announced Samsung official website.
In order to perform the conversion task, a powerful Video Converter is needed definitely.
