Two main differences between CD's and DVD's.
The first is the size capacity. A CD can hold 700 MB while a single
layer DVD can hold 4.7 GB. That works out to roughly 45 minutes of low
quality playback compared to roughly 80 minutes of high quality
You can put a video on a CD. The quality won't be very high since the
supported bitrate is very low. I forget, been years since I burned
one, I think it tops out around 1,700,000 bps and is limited to using
MPEG-1, while a DVD can be encoded as high as 8,000,000 bps and uses
MPEG-2. There's differences in the relative frame size. A CD is
640x480 while a DVD is 720X480. This may not be that big a difference
if you only play back off a computer, but if you try to play off a set
top DVD player hooked up to a TV that means the DVD player has to
stretch the frame to fill the screen that much more and that will
further reduce quality.
