Whenever I rip a movie from a DVD, the movie seems to be around 695-725 MB. Regular DVD-R discs can hold up to a capacity of 625, if memory serves.
Most DVD's include games as well. After considering all the materials in DVD's, I'm assuming the the movie industry compresses them and stores them. But usually, compressing files result with low quality movies. Only certain formats that I know of H.264 seem to retain the quality, if not somewhat. How does the movie industry store such a large file in addition to the extra features in a single DVD? (Excluding those movies that require two movies. Such as Movie, and the other is special features.

Aren't those blue-ray discs?
blue-ray discs would probably hold more memory due to their high quality vids.

CDs hold 650 to 700 MB.
DVDs hold 4.7 GB (single layer) and 8.5 GB (dual layer)
Blu-ray Disc (BD) holds 25 GB (single layer) and 50 GB (dual layer)

VCD - format for storing video on CDs and uses MPEG-1 video compression
DVD Video - format for storing movies on DVD using MPEG-2 video compression
Blu-Ray - for movies on BD, uses MPEG-4 (aka h.264) or VC-1 for high-def video compression. A number of Blu-ray titles have used MPEG-2 compression.

I just purchased a case of 30 at Walmart for $13. 4.7GB and all that.

Just to add to the question, I know some longer movies are on a dual layer DVD. Is there any place I can buy a few dual-layer DVD-R's?

Thanks

Note all prices are in US dollars and cents.

CD-R discs costs pennies per disc.
DVD-R or DVD+R cost dimes per disc.
DVD-R DL or DVD+R DL cost a dollar+ per disc.
BD-R costs several dollars per disc.

You can find dual layer (DL) discs at Walmart, but it's a specialty item for such a store and the price might not be good. I would suggest Sam's Club or Costco if you want to buy them in a store. Otherwise, shop online for good prices.
