Mpg is the only format that seems to work well on all platforms. Mac users, not sure about Linux uses, can view wmv files but the player sucks. Also mpg, unlike wmv files, can be easily protected with htaccess.
I'm a Mac user as are my associates so we use all Mac programs.
Angel does the editing in iMovie since it is so easy to use.
Then we bring it into Final Cut Pro to finish them off and add the copyright and turn the .dv files into mpg files.
To batch spilt movies we use
ffmpegX.
