DVD-R Capacity

I'm trying to make a copy of a dvd movie for my library but I don't know if it is possible to compress a movie into a DVD-R disc. The movie is 7.5GB but uses only one disc. How is this possible since most DVD-R discs available can only hold 4.7GB.

Thanks.

a dvd can be upwards of nearly 10GB . unfortunately those are special ordered by movie production companies, and not available to the public. if you just want the movie with no chapter makers or extras, you can rip the video and audio and compress them. then put them together and burn them and itll be less than 4.7GB

theres a thread on how to do this. Copying DVD's Tutorial

Dual Layer DVD's are 10$ each and are available in stores. They can hold up to 8GB and are what some Production Companies use.

Yep, basically a dual layer DVD has 2 information layers on top of each other = double the capacity.

That's what nearly all commercial DVD's are, some also have 2 layers on either side of the disk, but these are rare.

Dual Layer burners and disks have been on the market about a year now...
