winff is a nice cross-platform GUI for ffmpeg that saves you having to
fight with the myriad of confusing options ffmpeg gives (mencoder is
even worse). The big advantage over using winff is that it has many
useful presets such as ipod/iphone, DVD, SVCD, widescreen avi etc etc
to save you the painful trial and error involved in wrestling with
vanilla ffmpeg. winff also makes batch conversion of movies simple.
Don't be deceived by the 'win' bit - winff runs on Linux as well as
windows!

Good point about medibuntu though Pete - if your friend is using buntu
Anna tell them to add the medibuntu repos before installing winff as
it will install a more capable ffmpeg that will handle more formats.
