I don't know the technical reasons but DV takes a lot more power to play
than dvd on my machine as well.  On an athlon xp 2800 (2088 mhz) with
matrox g400 using xmga, playing a 720x480 ntsc dv file with qdv, ffdv,
or libdv, cpu usage hovers just under 30% according to gkrellm.  Playing
a 1.33:1 dvd, cpu usage is sporadic and under 15%.
