DVDs have a different format than CD-Rs. CD-R is mostly used for music, and DVDs are mostly used for movies. When you burn mp3s into a CD-R, they convert it into an audio format where you can play the CD in any CD playing device. A 5 minute music file is approximately 5 Megs. A movie format is in a totally different format. They usually have an AUDIO_TS and a VIDEO_TS file where one plays the movie itself and the other has the movie Audio. The format for movies are usually in .vob format. A 30 minute movie file is approximately 1.5 GB...if you do the math on it....5MB is approximately 6 seconds of a movie.
That is why they are both marked differently, because you are comparing apples to oranges when it comes to the file types. There are some file types that are smaller or bigger than others even though their playback might be the same minutes. An mp3 file and a wav file might have the exact same music content, but normally wav files are a lot bigger than mp3s.
When it comes to quality of the movie file, DVDs were specifically designed to copy movies. CDs were designed to copy data and music files, so you will see a difference in quality when you try to burn a movie in a CD-R and a DVD.

I think DVD time refers to video, and CD time refers to audio, as DVDs can hold hours of music and Cd's cannot playback "DVD format" video.
Also, your standard DVD's (dvd5) says it's 4.7 gig but is really only like 4.4
