How many bytes are in a DVD movie?

when we're talking about DVD movies thinking in terms of how many bytes is pretty rediculous.

a very short DVD quality movie will be measured at least in tens of mega-bytes (Mb).

one megabyte is equal to 1,048,576 bytes. so, if you were, for instance, thinking in terms of how many bytes there were in a full-length DVD quality feature film then you would be talking about gigabytes(Gb). one Gb is equal to 1,073,741,824 bytes.

you need between 1 and 3 gigs of space for a whole DVD worth of information.
