XENOPHILE  For $39, this should not preserve original content protection (funny how the developer advertises this as if it's some sort of feature).

Check out MacTheRipper (free) or RipIt (cheaper) for a solution that rips DVDs without combersome limitations. Fast DVD Copy offers more features than RipIt but at a steep price. RipIt is newer and being developed at a fast pace, hopefully it will soon match FDC's feature set.

ESCAPERAISE  Totally love this app. Simple, fast, copies DVDs old and new.

Now my DVD collection is my backup, no more shuffling through stacks of plastic.

If I were to nitpick, I'd wish the file size were smaller, on the order of iTunes, 1 GB instead of 7 GB.. Even so, the paid version is the best software purchase I've made in quite a while. And the free versions worked fine for me as well.

CAPIAUMATADOR  My dear fellows, the most common thing I have found so far on Mac is an impressive number of third-party programs that can do exactly the same the main OS can do. Drive-in is an ilustrative example: its idea is great, but I am able to do what it claims using only Disc Utility. Lets go: consider that I am using the Portuguese version of Leopard, so the names may vary (but the procedure is the same). (1) Open Disk Utility; (2) Insert the DVD you want to rip or copy; (3) Select the DVD drive on the left and press the New Image button on the top (4) On the popup menu, give the disc image a name, and choose from the menu “image format” main DVD/CD (or something like that). Choose where to save, and save it. What is important is that it will create a file with the extension .cdr, which is a DVD/CD Master Image type.

Well, you now have exactly the same DVD on your HD. Click twice on it (it will mount), then lauch the DVD player. DVD player should begin to play automatically. All menus and adjusts are fully functional, as a regular DVD on the optic drive. All this procedure took around 10'12 minutes.

Am I missing anything?

CHARLES TETON  Love it... What more can I say...

AT  I thought this app was dead already. I actually like this app. With this, I can create a cheap-man version of the Kaleidescape system. But both Kaleidescape and Drive-In are region code specific. If Drive-In supports multiple region codes, I don't mind paying more for the software. The region codes thingy is a stupid concept and should be abolished altogether. Another worrying thing for me is, if Flip4Mac folds, I will have a headache in future if Apple decides to change something in its future OSes. Then we are all f***.

ZEPHYRIS  Why do you need to enter the bar code number from the dvd disc just to download Info from Amazon? Shouldn't the disc information be auto fetched to begin with? This is pain staking and a waste of time. To catalog dvd's this wouldn't be my number one application.

VANDAL  This is the type of app I've been looking for for a while. It's nice to have perfect quality one for one copies of my favorites right on my hard drive when I travel, and the "DVD cases" are a nice touch. Although the images take up a good bit of space, I keep my main library on a backup drive and rotate images on my Macbook before I leave for a trip, or simply take the drive with me. It suits my personal needs perfectly and I'll defnitely be purchasing this app when it comes out of beta.

As an aside, for those who complain about no compression or removing encryption, read the description. There are no surprises here, and it does exactly what it says. Granted MTR is free, but it doesn't work with all DVDs and these days you have to jump through hoops to acquire the latest version.

ISILVER  I picked out two DVDs, and couldn't get either converted to DVD.

The first, "Edgeplay - The Runaways Movie" was found in the Amazon database (which is where I brought it) but DriveIn complained about not being able to do something to the CSS, the second, "Charlie and the Chocolate Factory 2 Disc Deluxe Edition" wasn't found in the database, must be because it is a Region 4 disc ...

Maybe I'll try again later ... maybe I won't, maybe I'll give the other apps suggested a go instead.
