This is very bad. For one thing, any framerate weirdness in the source
DVD will lead to A/V desync or damaged picture in the output file.
This is especially problematic if the movie is a fake-telecined NTSC
DVD, or even worse, mixed fake and real telecine. Also AVI files can
only be 2 GB at most (otherwise you can't have index and stuff might
get screwy), and most DVDs are much bigger than 2 GB.
Instead, use: mplayer -dvd 1 -alang en -dumpstream -dumpfile foo.vob
Or better yet, if you can keep the DVD for the entire duration of the
encoding (i.e. if you're not a cheapskate who rented it from
blockbuster to rip ;))) just encode straight from the DVD!
