What am I doing wrong?!?!?!
First thing you did wrong was buy 123Copy DVD Gold. This is not a program many of us around here will be familiar with.
To get you started on the right track, you should download DVDFab. There is a free section of DVDFab called DVDFab HD Decrypter. It will continue to function even after the trial for the main part of DVDFab expires. You can find it here: http://www.dvdfab.com/free.htm
DVDFab is still updated to deal with newer protection schemes as they appear, which is one reason I recommend it. The other is that the important part, the decryption/ripping section, is still free to use. While you have the trial for the main part, you might explore its capabilities as well. DVDFab is an all-in-one program for backing up dvds.
Use DVDFab HD Decrypter to rip to the hard drive. There is a full guide to the program at their website: http://www.dvdfab.com/docs/
While you have the trial, you can use it to do all the work necessary, but eventually you'll need to either buy the program or use a free compression program along with DVDFab HD Decrypter. I recommend DVDShrink for this.
DVDShrink can rip/decrypt movies that only have simple CSS protection, but it is still a fine program for compressing a commercial dvd to the size necessary to fit onto a single layer blank dvd. There are many guides to using DVDShrink here at cdfreaks in the Movie Copy Software forum, and at sites like www.mrbass.org and www.dvdshrink.info To download DVDShrink just click on it in this paragraph (first word of this paragraph) and it will take you to the download site here at cdfreaks. DVDShrink is free to use.
Once you have the dvd ripped, compressed and ready to burn, you should look at a program called ImgBurn to do the actual burning to the disk. It is free also, and is a favorite around here. Burn at a moderate speed, so if your disks are rated at 16x, try 8x or 12x in a desktop dvd burner.
+R or -R doesn't usually matter as much as getting good quality. We recommend Verbatim brand 16x disks as a safe bet on media. I'd stay away from RW disks, unless you have a specific reason to use them.
