VLC is buggy and quirky most of the time.
I've not bothered lately. VLC, on my machine, seems to crash way too often with mpeg-4 files, so I use Niceplayer with Perian. My own experience, as simple as that, so leave it at that.I use VLC for all my local videos. Works great. Except the speed of sound cannot be changed. I forgot if mplayer can do it
