After years of using VLC as my video player of choice I came upon Chroma Player. This is how a video player for the mac platform should look and act like. Used it for the full 15-day trial period and never had a crash. Much more stable than VLC but the best part is how it renders subtitles using the native resolution of the monitor instead of that of the video file (like VLC). The result is crisp text that doesn't strain yor eyes. Also try using the transparent background subtitle style (the animation of the text box is wonderful). I love Chroma and use it a lot so I wrote a Sofa Control script for that (it's in the new version of Sofa Control).
I hope the next versions will add playlist support. If you like me are anal about type (and if you're using a mac you should be) and view a lot of movies with subtitles then Chroma is the player for you.
