I am attempting to settle a dispute and I need clarification from all of you on TWW.

When taking an image of a DVD and copying it to blank media, the blank media is totally full (4.** gb) or quite close. On the other hand, when simply downloading the video/audio files, the files are often in the neighborhood of 800mb. I was under the impression that the larger size seen when ripping dvd iso images is a result of copying the empty space on the disc as well as the files themselves. In other words, is the 4+ gb iso just the movie plus a couple gigs of randomly inserted empty space that is there for security encryption purposes. Am I right at all on this, or am I bat shit crazy?

no

how the hell would it have anything to do with encryption if it was blank space? think about what you're saying

yeah, because people change the bitrates of the media so they're easier to transfer..and sometimes so they'll fit on a CD instead of DVD

the files you download are typically compressed with a more lossy codec (e.g. DivX, etc.)

the video/audio VOBs on a DVD are straight up mpeg 2. they take up a lot of space.

generally speaking, when it comes to audio and video, higher file size == higher quality. this isn't ALWAYS true, though.

Your friend would be justified in smacking you if you were arguing about this.

Most movie dvd's are dvd9s, so the iso is around 8gb.

Totally separate question but also for ISO's. Is there a good program (prefer freeware) that can take ISO images from a hard disk or apply ISO images that i get from others to a hard disk.

Trick here is I need it to run on my windows thumb drive, could maybe have a server echo type thing to that would be helpful. Really anything at this point cause I dont really have a reliable program that I can use. Thanks

^Nero ImageDrive, MagicISO, DaemonTools, PowerISO, CloneCD/DVD all do that.

if you copy the DVD files directly (*.vob) or if you make an ISO image, it will be a 4.7 or 9.4GB

if you decode the DVD and re-encode in DivX/Xvid or whatever, typically most converters put it at or around 700MB to fit on a CD.

Cool, I was already using MagicISO to a small extent, and I was looking into others as well because in some cases it wasnt quite cutting it. Everything I'm doing right now is in .iso format so the encoding shouldnt be a big problem. I was just looking to get the most flexibilty from existing applications as I could get as far as creating and applying the images. Thanks
