How does this program actually work? I've made some back-ups of my DVDR's already, and compared them to their original and there's no noticible differnce to me.

I don't really know how it works, but if you try watching it on a large screen TV, you can tell the difference. Also, when a movie is particularly long, there's also a difference in quality.

oops, didn't read your post correctly. If you backed up DVDR to DVDR. You shouldn't see a difference. If you backed up a dual-layer DVD or DVD9, you'll see the difference if your movie is comparably larger than your DVDR. The source's quality has a lot to do with it.

The program actually does a "compression" not by compressing the movie but by dropping unnecessary frames. (without going into detail)

The more video you want to put into the 4.4gb dvd the more frames are needed to be dropped. As such, the disk copy mode, will have a slightly worse looking quality (due to the fact you want to put more video into the 4.4gb output) than the movie only copy.

For standard non hd/widescreen televisions its rather difficult to see this difference (unless you get up close to the screen and stare hard during a fast action scene) But with the distance from the TV to the couch its blended and really hard to tell a difference between the movie only and the disk copy (and for some even the source dvd)

if you have a HD or large screen tv, the movie only copy will look better since you are keeping more of the frames denoted to only just the movie part of the dvd.

hope that helps some.


Now to the dvdr to dvdr - since they are already at 4.4gb you wont see any difference (why you use dvd2one on a dvdr already is strange).
you can just do a direct copy with a dvdr since its already been decrypted and fit down to 4.4gb.

Not to sound like im raindancing on anyones picnic, but i used a dvdshrink (which im sure has the same method as dvd2one) on Love and a Bullet which was originally 7+ gigs, and i sucessfully fit it on a dvdr using level 4 compression. Watching it on my 57 inch, and the only reason i could tell it wasnt the original, was becasue i made it. = )
