I, too, am having issues getting subtitles to work. In my case, I'm using Convertor to take an already ripped video, with subtitles that work fine on playback, and attempting to use "Direct render to video" to hardcode the subtitles into the video. This has worked fine in the past, though I haven't used it for a while. However, with 11.1.0.4 (32-bit) and 11.1.0.6 (64-bit) it isn't working. I've tried using different subtitle streams, all of which I can view during playback of the original file. However, after conversion, they aren't hardcoded into the video and the subtitle information that was in the original source is gone.
