Can DVD-Rom Software Discs Be Copied?

[tbarrnes]

Is it possible to copy a DVD-ROM disc which is larger than 4.7GB? Are there larger capacity discs available, and if not how do the software companies fit so much on one disc?
Thanks Travis

For a DVD-Video disc try DVDShrink. It takes a dual-layer DVD that's as much as 8 or so GB and recompresses it down to fit on one single-layer. It works quite well.

For software I don't know if DVDShrink will work. I doubt it. Software doesn't tolerate lossy compression well You may be stuck with WinRAR or WinZip.

There are dual-format burners on the radar screen but they're still months off for DVD+R and as much as a year for DVD-R. They will burn DVD-9 dual-layer discs which are 8+ GB.

PLEASE only post video related stuff in the video forums. I'm moving you.

Sometimes they compress the data, so get more on a disk.

They can fit so much because they use pressed dvds rather than burnt Dvd (unless they are really only going to produce 100's) that means the blanks have a capacity of up to 18gb (and they use compression)

Alcohol 120% would allow you to make an image of it and mount it as if it were a drive i.e. assign the image a drive letter i.e. f:\ and the computer thinks that the disc is in the drive.
