This is the screen you'll see after DVD Shrink has loaded the DVD.
(1) These are the contents of the DVD by category. If you select the category you can edit all it's content as I have done here. I you want to change the settings for each video track seperately you can click on the + sign and select each one of them. When you select one track or category you can change the settings in the right, that we are going to explain right now.
(2) Here you can select the compression. The bigger the % number is, the better quality you'll get. The options here are Automatic, that selects the right compression to fit the DVD automatically, Custom Ratio, which lets you select the compression you want (usually used in the extras to lower the quality and gain a little bit in the movie). Keep in mind that you need to have a look at the green bar you can see in the top and make sure that your project fits into a single DVD. Over options are Still Image, which replaces the video with an image and you use it when you want to remove that video track and Still Pictures, which replaces the video with compressed pictures from the movie taken evey few seconds (pretty useless, unless you want to keep the audio).
(3) Here you can select the audio tracks you want to keep. Be careful as some tracks may be director's comments, view the DVD to make sure what is what and make the right selection.
(4) Here select what subtitles you want to keep. Even if they seem small, they take some space, so keep the ones you really need.
Let see an example.

Let's demonstrate some things you can do with DVD Shrink before we show how to start encoding!

When you're unsure about which tracks to keep and which not you can use DVD Shrink's preview feature. Just select the track you want and then click Play in the preview area. You can now watch the track and decide weather to keep it or not!

Every track you don't want to keep, you can just replace it with a still image. Removing it doesn't exist because that would change the DVD structure. But you don't have to worry. Just select the track you want to remove (all the whole extras category if you want to remove all extras), then select Still image in the video compression drop-down menu and that's it! You can even select your own image to use by click the Browse button!

To bring up the backup options screens you just need to click the Backup! button in the toolbar in the top of DVD Shrink window.

First options screen is the Target Device one. Here you just select what to do with the DVD files DVD Shrink will create. The first option is to burn the files with Nero (you must have it installed). If you have CopyToDVD installed this option will appear also. Also you can create an ISO file and, if you want, burn it afterwards with DVD Decrypter. Be careful because this does not mean you can burn just with DVD Decypter as you need Nero installed again to create the ISO file. Finally you can just output the files in a hard disk folder and then decide how to burn them.
The "Select folder for temponary files option" above the back-up target one (hidden by the menu here) is the location that DVD Shrink will put the DVD files before burning them. Make sure the hard disk you select has enough free space and that you remember where they are as you have to delete them manually after the burn.
We are not going to go through the DVD Region tab, as you just leave everything to default (just select Region Free and leave Provider ID empty). Now you are ready to click the Quality settings tab.

Here the things are pretty simple. If you want the encoding to take the less possible speed leave these two options unselected. This will increase the speed. In the other hand if you want to have the best possible quality you should enable both of them, but be ready for a long encoding time. If you click the "What do these options mean?" link in that window you can read more about these options in DVD Shrink's help. For your convenience I have uploaded this document and you can read it here.
Now click the Options tab.

Here select "Run backup in low priority mode" if you want to use your PC while DVD Shrink will encode. If not (I suggest you leave it alone!) then deselect it. The other two options are obvious so make your selections and then click the Burn Settings tab.

The little thing you need to know about is re-author mode. Let's have a look.

To enable re-author mode click the button in the toolbar (1). What this mode does is pretty simple. It authors the DVD again so that you just keep only what you need. When you press the button the screen changes like the picture above. From the DVD Browser (2) you can drag-and-drop the tracks you want to keep in the Re-authored DVD area in the left (3).
Here's the point that needs some more explaination. You can add whatever you want, BUT the menus will NOT work. Which means that you'll see the menu animations like a video and you won't be able to make any selections. So you understand that you should not add the menus.Without the menus though, there is no easy way to see the extras (you need to use your standalone's controls to move between the tracks, not being able to see which track is what).
So you easily understand that the re-author mode is meant to be used when you want to keep just the main movie. Actually re-author is the best way to copy big films like Lord Of The Rings and others over 3 hours. When you want to keep the menus and some extras use the guide as we showed above. When you just want to keep the main movie, use re-author!

Well after this huge guide I hope you are a DVD Shrink master! If you face some problem don't worry, just come over to our forums and ask - we'll be glad to help!
Happy dvdshrinking!
