Alpha ... you're way off base here. I doubt that anyone here is actually
stupid, just ignorant. Ignorance can be cured by education but there is no
cure for stupidity. Here's a little education for you.

DVD's hold a binary representation of something ... it doesn't care what,
just a buncha one's and zeroes. This can be a few minutes of raw
uncompressed video, a 3 hour compressed movie, 4.5 gigs of wareZ or your
granny's recipes. Neither the disc nor the recorder care one way or the
other. The maximun size of the data file is a fixed value.

How much video you can fit into the masimum DATA file is primnarily
deterined by video bitrate. DVD compliant video has a maximum bitrate of
9,800 kilobits per second. You cannot fit 2 hours of 9.8Kb video on a single
layer recordable DVD. To make it fit, you must reach a satisfactroy, to you,
compromise between bitrate and quality. How many minutes of video (how much
is a fixed value) you can fit on a single layer recordable DVD depends
entirely on how much you are willing to compromise.
