Length of the movie compared to file sizes ????

[Athlon]

i recently went to rip a movie ( just the movie, not the entire disc ) and was surprised to find that although it was only 70mins long ( Toy Story ) the files that made up the movie where just short of 5gig



i thought the general rule of thumb was if the movie was around 90-100mins it should fit on a blank DVD-R, but i have since noticed more movies that are around or under this time limit, but the file sizes are over 5gig. Is this some re-encodeing, done to stop guys like us ripping the main movie to a single disc ??


thanx

Filesize and Movie length do not change equally.
There is also bitrate of the video, format of the audio streams and the amount of audio streams.

E.g.: A video of 90mins at max high bitrate uses more diskspace than 120mins at lowest bitrate.

Also, for audio, a 6channel track uses more diskspace than a 2ch track. Not to mention DTS tracks which take up more diskspace that DD tracks with same amount of channels.

It could also be that your 70min movie has 4 audio tracks, compared to your 120min movie with only 1 audio track.

A 5GB DVD is not made for copy protections or whatsoever. It all depend on its contents and its quality.
