Yes, subtitles in DSplayer are prone to random bugs. E.g. I have absolutely no problem with multiple embedded/external subs, but have a minor issue subs bigger than normal in the first 3-4 seconds of any video.
And since those issues cannot be reproduced consistently, the developer cannot do anything about it (as he explained).

I have both problems, but as the developer isn't hanging around here, I can't tell him the possible reason for the second problem you (and I) have: Over 1000 fonts installed in Windows.
