LOL Funny how they recognize the problem, and steer you to the workaround without having to know what the heck is wrong!
Alright, since I'm a fast typer, I'll give you the article, in its entirety:
You shouldn't confuse 123 Copy DVD with the now-defunct 321 Studios' DVDXCopy, but we can see how you might make that mistake, what with the similar packaging and the whole "321" and "123" thing.
Unlike DVDXCopy, which lets you burn movie DVD's right out of the box, 123 Copy DVD doesn't touch copy-protected movies - unless you download an additional plug-in, which just happens to snap right into the program. In other words, 123 Copy DVD manages to skirt the thorny legal issues.
Once we obtained the small plug-in we were off and burning. 123 Copy DVD capably transcodes video, even in cases where the movie is too large to fit on a single-layer disk. Out of the box, the program doesn't yet support dual-layer discs, but the company says it will soon add the feature.
We used the exceedingly long director's cut of JFK to test the program's transcoding abilities. All other DVD copying programs we've tested have produced unsatisfying output when it comes to this oversized, three-hour-plus movie, but 123 Copy DVD performed admirably. We compared the output from it with a disc made using DVD Shrink, a freeware DVD transcoding and ripping program that's popular among the staff. 123 Copy DVD's copies generally looked better. While DVD Shrink can be tweaked for better results, we think the two apps are for different audiences. DVD Shrink fans are advanced users, while 123 Copy DVD users are likely to be the fire-and-forget crowd.
One feature we like in particuar is that 123 Copy DVD doesn't force you to activate the app online like other commercial DVD duping programs. When developers put this restriction on their software, it means your ability to reinstall the app in the future depends on the continued existence of the company.

Hmm. Typical sales pitch but who can blame them.
Let's see. They claim their product 'transcodes video,
even in cases where the movie is too large to fit on a single-layer disk.' That's a bit of a strange statement coming from them. What they should be saying is their product 'transcodes IF, and ONLY IF the movie is too large to fit on a single-layer disc'. Otherwise there is no need to transcode. Still need to decrypt though. Maybe that's what they meant.

And they mention DVDXCOPY, which admittedly is a piece of junk. It has very bad problems with reds for some reason.
And since they're testing 3 hour+ movies, here's one I did for a mate a while back. I took his Lord of the rings special editions (1 and 2) and combined each entire film onto 1 dual layer dvd+r. For those who don't know, (all three of you) each of the film comes on two dual-layered discs. Reason being, he got a bit sick of having to swap discs half way through and his copies were already a bit too worn. Using DVDshrink, took out the menus, all subtitles except for the forced subtitles, and all audio except the DTS track and ran deep analysis. What resulted was 65% compressed and great quality. Of course it wasn't just like the original but on the projector, a friend's plasma and a CRT it looked more than acceptable. Macroblocking was visible on the projector only when I paused it and looked very closely.
As for DVDshrink being for advanced users, that's a (small) load of crap. I was actually introduced to it by a friend who's computer skills don't extend much further than 'ON' and 'SHUTDOWN'.
Now I'm not saying the program is bad for being fire-and-forget.
But why pay for the MPAAs stupidit. MEANING: All the protection they put on DVDs is the equivalent of sealing a bank-vault with chewing gum. I'd rather do it for free.

One bad thing, this program makes the whole thing too easy. No more video capture, compression and VCD authoring. I guess it's a bit like ordering a premade MAME cab rather than converting/building it yourself.
I'll shut up now.

Like the new smileys.
