Sbtitles, keys and frames.
 

I wish you made a key definition that let you jump back/foward to previous/next sublitle time. So you could scroll subtitles if you didn't have enough time to read it, sometimes it just blink, and it is imposible to read it or catch a moment to pause it and then read. Usually it takes much time to rewind and find the moment and try to read it again, so it could be done in one touch - you press a key and it jumps to the previous subtitle time and pause playing, letting you paecefully read it(oh that impalpable subttle^_^).

In the v1.36 much of my DVD video was stuttering 'cos my PC is sLOW, in 2.15 it's flying... with a variable speed. Looks like it keeps trying to keep showing all the frames without loosing any, but when it get the point, that still it couldn't do it, it start skipping the frames to catch up. This reminds me a pitching on a ship. Can you make an option to make the frameskip stable?
