The 'x'-number is different for CDs and DVDs. For CDs, Nx means 150 KB/sec
times N, whereas for DVDs it's about 1.4 MB/sec times N. Some DVD drives
also are much slower reading movie-DVDs than they are data-DVDs.

FWIW, it takes me about 25 minutes to rip an entire DVD as ISO using mythtv,
which is a few minutes slower than using 'dd' to do the same.
