If you see the files on the disc and they just won't play in your player then it could be because of the format. I know most of my DVD players (including several older Sonys) won't play +R. Most modern ones will play both formats. If you see nothing in the folder then you're doing something else wrong. Here's the simple steps you should use..
1. Insert disc and when it's done loading open Decrypter (good idea to turn off auto start on your drive or that stupid Interactive player thing will try to insall (I hate that thing).
2. After Decrypter opens hit the decrypt button. Occasionaly it'll find the area protection on it and it'll pop up with a window for your zone. Just hit ok.
3. Make sure you notice what folder it's going in, sometimes it picks stupid folder names like DVD_Video. really original there..
4. Close Decrypter and open Shrink. If you want the entire disc just Shrink it to fit, but if it's a typical DVD then it's probably close to or more than 8 Gb's. Chances are the compression will make it either look like shajt or it wont' play on your player. around 6 Gb's seems to the max.
5. If you only want the movie then hit that recompile option or whatever it's called (don't have my computer in front of me here at work..). Just drag and drop the video (it'll be in the middle group and the largest file) over to the left. The menu group at the top is usually crap and it won't work if you break the movie up. Sometimes there will be two different movie files, it's usually wide or full screen and you can use the player in the bottom left to see which one is which. The bottom third of the menu are the extras. Most of them are garbage, like the copyright warning screen... Just take what you want and drag it over to the left. You can move everything on the left side up and down by dragging and dropping and it'll play back in that order, top to bottom. You can also click over to the DVD menu tab and get rid of all the extra audio options and subtitles. That'll free up a lot of extra space. The default is English and Dolby 5.1. DTS isn't checked by default for some reason, so I always uncheck Dolby 5.1 and check DTS because I prefer DTS.
6. When you're done hit the shrink button and specify the folder you want it in. I usually use the same name and add 2 burn at the end so I know which is which. Once you've shrunk it you can delete the original folder. Burning DVD's will eat a LOT of HD space real quick...
7. Once it's been shrunk open Nero and click on the DVD Video button. You can label the disc from the first menu and do other things, but I usually just close it. Find your Video_TS (and Audio_TS if you made one) on the explorer looking thing to the right. Drag it (and the audio if you have it) to the left. Once it's over their you just have to hit the burn button at the top. That same menu will pop up and you can add the label and anything else you want to it. Then just kick back while it burns.
Really easy to do. If this doesn't work then you have some issues somewhere else..
