In that case they're MPEG2 files, which *are* compressed. Granted, the
compression isn't as good as other codecs like MPEG4, but there's
compression none the less. Uncompressed NTSC video would use up roughly 30
megabytes per second.

Oh, and K3b isn't burning anything. It's merely a front end to dvdauthor
(to create the DVD-Video structure from your mpeg2 files), mkisofs (which
generates the UDF filesystem to burn to a DVD-Video) and growisofs (which
does the actual burning and can indeed invoke mkisofs itself).
