I'm glad I did this. I'd been trying to evaluate all of these players for a while now, but kept getting confused about which had which problems, and I'd decided that all of them were awful. Going back and writing it all down, I was surprised to discover that while it didn't have a lot of playback options that I wanted, Movist really had no problems, so I'm going to be switching to it (from VLC).

I'm sure I'll find that one showstopper for it before too long.
