Hi all. I’m using Panasonic 49" 4K Ultra HD Smart TV TH-49FX500K and I’m having issue with my smart tv which subtitle srt file is not appearing when I played mp4 file movie. I did re-name the files & even hardcode the subs with the video but still no subtitle appear. I’m really clueless right now & I don’t know what to do Is anyone having this kind of problem?
