Is there a way to globally set the default video player in Ubuntu 10.04 (and soon 10.10) to VLC? (unless you really think there is another, higher performance player, in which case do let me know)

One way is to right click, say on an AVI file, select 'properties' and select the 'Open with' tab. Select VLC or add it and close properties. From then, all AVI files will be opened with VLS.
For DVDs you can go to Panel menu > System > Preferences > Removable Drives and Media and go to the 'Multimedia' tab and change it from Totem.
