Someone want to explain to me how Intervideo can sell their util for "backing up" your DVD's while someone like DVDXCopy cannot? Am i missing something here?
Seems like it is just you, i've backed up a lot of movies and didnt have any problems. I've noticed some pixelation in fast paced scenes but thats only when you go below 60% compression.
i tried dvd shrink and i really didn't like it.
i first use dvddecrypter, then dvd2one, and burn with copy2dvd
i always get flawless dvds no matter how much compression

I don't know if it's been mentioned before, but animation does not compress well. Since animation is a group of flat colors there is nowhere to hide the compression artifacts. Make an half red hald blue image and save it as a bmp. Then take that BMP and compress it to 50% JPEG and see if the colors stand afterwards. Its the same way with regular animation. With regular movies, since more colors are uses, it can compress certain colors by blending them together. Animation images can't be blended as easily.
Whoa.. ok - so here's what I see from this.
1. DVD shrink offers multiple ways of reducing size. 1 is compression, other is removal.
2. OP asked about compression settings because his results look like crap.
3. Most of you people who say Shrink is great - are saying it's good when you don't have to do compression.
therefore, Shrink is only useful for DVD's that have enough extra features (that you don't want) to completely or nearly completely avoid using compression. Considering the whole point IS compression - I'd say it can't be that good a product. There's a HUGE difference between "watchable" and "phenomenal" and DVD Shrink sounds like the first.
CZroe, if you are comparing your cell phone pic and then saying your DVD shrink backups are 2-3x worse than that while in motion, something is definitely wrong with your individual setup.
Oh, and congrats on having probably the longest post of all time or at least that I've seen

more like Netflix I'd imagine
Agreed. DVD Shrink is great for the titles where you can get rid of extras and then have very minimal compression, but for a movie like Casino, where the movie itself is already like 7.5 gigs, then DVD Shrink is probably not the best tool to use. I'm not going to spend more then an hour total backing up a DVD because if it takes that long, and you actually own the DVD, then I think it's worth it just to go buy the damn DVD again if something ever happens.
If you have the time and care enough to make a flawless backup then more power to you. Most people can't tell the difference, but say an extra thanks at night for having good eyes.

Yes, DVDShrink sucks. All those programs do. *ANY* recompression, even if its only 5% is still significant because you're recompressing an already compressed file.
Anyone who thinks otherwise is watching movies on a piss poor setup, and if it looks good to them...well, more power to 'em.

I don't really know anything about DVD technology, but wasn't it because DVDXCopy bypassed some form of protection or removed something in the process of copying the DVD that made it illegal? The other softwares out there do the job differently and legally. I guess that's what makes software selection so critical, because they are all doing it differently and thus you get different results
Looks like a lot of people in this world have piss poor setups then. If you have enough money to buy and put together a great home theatre, then you probably have enough money to replace a broken DVD every once in awhile.
A lot of people here who are saying that they can't tell the difference between a DVD compressed with DVDShrink and the original DVD are most likely watching their DVDs on a standard TV. I personally haven't tried DVDShrink, but I've tried other programs before like DVDXCopy and while the results of DVDXcopy on a normal TV are great (I can't tell the difference), if I watch the same DVD on my HDTV with a Progressive Scan DVD player, all of the compression artifacts jump out like crazy.
Simply put, if you're taking a DVD and compressing it down by 50% (for those who are taking a full DVD-9 and squeezing it onto a 4.7GB DVD±R), there is going to be some quality loss. MPEG-2 is not a lossless compression format and while you may not be able to tell the difference when you're watching on a TV with half the resolution, you'll be able to tell when you're watching at the standard 480p resolution that DVD supports. For those who are removing most of the extras and compressing a small percentage, you probably won't be able to tell as much of a difference.
I can't offer any direct advice for DVDShrink since I've never personally used it. But if you try and do like others have suggested and remove as much content as possible so not as much compression is needed, you'll most likely have more success. It was already said before too, but anime does not compress well either. You'd think lots of solid colors would compress great, but MPEG2 is not designed to compress solid colors. Its meant to compress regular pictures with lots of different colors. Sortof like how pictures with lots of solid colors compress and look better with GIF/PNG than with JPEG while pictures of real people compress and look better with JPEG than with GIF. Try a regular movie and I'll bet you'll be more sucessful with DVDShrink.

Nah. I'm only talking about the intro to Cowboy Bebop which resulted when I ran "automatic" as my first attempt before really getting into the nitty-gritty of DVD Shrink. Because it was just the intro, I wasn't really complaining about it. It's just the only thing I could visualize in the post
Like I was saying, I actually would have set that to "slideshow with no audio" if I had bothered with the first rip. The successive attempt at Cowboy Bebop I DID remove everything possible and the feature NEARLY fit without compression and it didn't make a difference. The rip still sucked when the movie started (Sucked like the first, not sucked like the menu/intro).Oh, and I didn't type much to add in that post. Most of that was quoting intended to direct my responses so you can skip over what you've already read (A good 85%?).
No, their product only backs up unprotected discs making another illegal product, DVD Decrypter, necessary.

bah, so what if a dvd breaks, your out what? 20 -30 dollars? is that worth wasting all that time/money backing up your collection? unless you keep the backups in a separate location, fires gonna burn it too
just wait for hddvd anyways, dvds not the ultamate format.

It's not about that. A fan/collector cannot bear to see a collectable scratched or thoroughly used. It should be archived and preserved for posterity/resale value. I cringe when I look at other people's scratched CD collections and wonder how they could possibly be pleased with this. I would NEVER let that happen to my DVDs.
