8.8 GB of MPGs on a 4.7GB DVD ? ? ?

I used Video Studio to export the video on a (non-HD) 4.7GB DVD to my PC. The total size of the MPG files exported is 8.8 GB.

The MPG frame size is 720x480. Bitrate is 9736 kbps. Frame rate is 29.97 frames/sec.

I'm guessing that Video Studio is not exporting the video encoded the same way as it is on the DVD. Archiving files twice as big as they could be seems wasteful. Is there a utility that will export chapters in the same MPG format as they are encoded on the DVD?

Single layer DVDs for sure.

I really just want to transfer my DVD videos to files so I can archive them long-term (lossless) on a hard drive. I would like to have easy access to the files anytime, --and also have them stored on something (like a hard drive) that won't disintegrate after 20 years or more.

I believe a hard drive will more likely be readable in 20-30 years than a typical DVD. Drives usually "wear" out with use, they don't warp or lose their magnetic state with time.

There are two problems with creating ISO's for long term storage. Videos saved as ISO's can't be directly accessed on demand. Also, in 20-30 years it may not be practical to go through the process of burning an ISO to a DVD and then finding a DVD player to view or convert the video.

It seems like there should be an easy to use application that strips video from a DVD's wrapper and saves it as an MPG that is the same size as what is stored on the DVD.
