DVD -> mp4 compression ratio

Hello All,

Merry Christmas! Of course mine came early with my Storm..., so I got a little head start... :)

I'm looking at putting a movie on my Storm, and was curious about the compression ration from a DVD format to a mp4 format. I started with the DVDfab5 and it says the conversion is 7.5GB to 7.5 Gb. Does the Handbrake software compress it further, or is that what it comes out to?

Thanks,

Terry
