3) DVD Decrypter
4) LAME ACM Codec
5) Virtual Dub

Step (1): Insert your DVD into the drive and launch DVD decrypter. DVD Decrypter will detect the DVD and its file contents will now be displayed in the right pane. Now go to File > Browse and select the destination for the ripped VOB files. Keep in mind that the destination must have enough free space to store the contents of the entire DVD.

Step (2): After choosing the destination, click on File>Decrypt to start the decryption process. DVD Decrypter removes the Macrovision Protection by default, and you can set to remove region code as well by going to Tools > IFO > Region > Patch > Region Free. These are necessary for the next step. After the DVD ripping process is completed, close DVD Decrypter.

Step (3): Next Launch DVD2AVI. Go to File > Open. Make sure the correct track number in the Audio menu is selected. You need to find the correct track number-most DVDs have multiple audio tracks in different languages. This can be checked by selecting one track at a time and playing it. Also click on the Audio menu and navigate to “48>44.1KHz”, and select Off. Go to Help > SIMD Technology and select all the optimizations supported by your processor. Now go to File > Save As AVI.

Step (4): Decide on a file name and choose a location with enough free space. You will now be prompted to choose a video compressor. Choose “DivX 6.x.x” from the drop-down menu where you can select the video compressor.

Step (5): Under the Certification Profiles, you can choose an appropriate preset profile such as High Definition, Home Theatre, Portable, Handheld, and Unconstrained. When you choose one of the above profiles, it is virtually guaranteed that the encoded DivX file will be playable on any standalone DivX-certified player. Click on Settings. You can select a bitrate of your choice. A higher bitrate means a larger file size and better quality, while a lower bitrate means a smaller file size and lower image quality.

Step (6): In the Codec tab, you can set the Encoding mode. The default setting is a good trade-off between quality and compression, but if you wish to control the file size, you can state your own mode such as High Performance, Better Quality, etc. Click on OK and then on save to start the video
demultiplexing process. This will take some time depending on the speed of your computer. At the end of this process, you’ll have an AVI file and a WAV file.

Step (7): We now get to the creation of the DivX file-putting together the video (AVI) and audio (WAV) files that were created in the previous step. Launch Virtual Dub. Under File > Open, browse to the folder where the AVI and WAV files are stored. Select the AVI file and click Open.

Step (8): Click on the Audio menu and click “Full Processing Mode”. Click again on the Audio menu and select “WAV Audio”. You will be prompted to open a WAV file. Select the WAV file you created earlier and click Open. Click on the Audio menu and then on Compression. Select “MPEG Layer-3” from the left pane and then select “128 KBit/s, 48,000Hz, Streo” in the right pane. Click OK.

Step (9): Select Interleaving from the Audio menu. Then, select the “mis” radio button and input “500” into the “Interleave audio every” dialog box. Click OK. Again, in the Audio menu, select Volume. Check the box and move the slider to 200 percent. Click OK.

Step (10): From the Video menu, select Direct Stream Copy.

Step (11): Go to File > Save As. Enter a file name of your choice at a location of your choice, and click at a location of your choice, and click OK. This, again, will take some time, but not as much as the video encoding using DVD2AVI. After the process is complete, you’ll have a DivX backup of ypur DVD movie.

Step (12): All that’s left now is to burn the DivX backup up to CD or DVD using your DVD-Writer.
