Hi, after upgrading to Hardy, the playback of DVDs no longer worked in VLC. I would get bright green/purple blocks everywhere and there would be lots of skipping. I solved this by changing the %u argument to %m in VLC's launcher, but I can't find out what the meaning of either argument is anywhere, does anyone know where to find the information or know why changing that argument helped? I like to know what I'm changing and why these things work, thanks
