Trying to add .sub subtitles to video using TEncoder; when I preview the video, the subs display perfectly, but when encoding is finished, there are no subs. I have also tried encoding with the .idx file selected, still no success. Any ideas? My system is: AMD FX6300 CPU, ASUS Sabertooth 990FX mobo, Radeon 7870XT GPU, 8 GB system RAM, WIndows Ultimate 64-bit.
