| First of all, to rip CSS-protected DVD to AVI format | | | | factor which influences the video quality and file size, |
| is possible with DVD decrypter program, but is | | | | by a field-test experiment. Feel compelled to follow |
| confined to legal use of the DVD only. CSS-protection | | | | me? |
| measure has long been the practice for preventing | | | | In this experiment, I will rip a 9 second segment of |
| commercial DVDs from being copied to hard disk or | | | | DVD to Xvid AVI in different Bit Rate settings. It is a |
| cloned to reproduction. But we are allowed to use | | | | repetitive action and I think it makes more sense to |
| DVD decrypter to clone our expensive store bought | | | | jump to the conclusion now. |
| CSS-protected DVD for DVD backup. As for DVD | | | | |
| backup, it only makes sense to rip DVD to a format | | | | It is all right if this conclusive data table confuses you. |
| with DVD-like quality, smaller size and high portability. | | | | It got me, too, in some senses. LOL. What is behind |
| So this is why we are going to rip DVD to AVI | | | | these data is an equation: File Size = (Video Bit Rate |
| format for the best DVD backup effort. | | | | + Audio Bit Rate) * duration /8. If you are |
| Normally, we need a DVD decrypter and a DVD | | | | perceptive, you would notice this is not an accurate |
| converter to accomplish the task. But now we have | | | | equation and there is small discrepancy between the |
| an integrated program with comprehensible interface. | | | | custom video Bit Rate and the actual video Bit Rate. |
| It is called Leawo DVD Ripper. | | | | It is because the Video Bit Rate is vibrant but |
| Leawo DVD Ripper is highly compatible with any | | | | constant. The actual Video Bit Rate reflects the |
| CSS-protected DVD. CSS-protected DVD will be | | | | average of Video Bit Rate. The longer duration of |
| recognized and automatically decrypted without our | | | | the video is converted, the more approximate the |
| interference. So let's focus on how to rip DVD to | | | | actual Video Bit Rate is to the custom Video Bit |
| AVI format in high quality, that is, DVD-like quality, | | | | Rate. |
| smaller size and high portability. | | | | Take a 2 hour DVD movie for example, you can be |

| Click open the "Profile" dropdown box, navigate to | | | | and High Profile. |
| "Common Video" to make a choice on AVI profiles. | | | | |
| We are going to use "Xvid Movie (*.avi)" profile, for | | | | |

| quality. Based on MPEG-4 compression, it can | | | | |
| guarantee the best ratio of quality to file size. As | | | | 600Kbps and Low Profile have just been crossed off |
| Xvid is an open-source codec, Xvid encoded AVI | | | | because of interior picture quality, while Medium |
| video is highly portable to be played on other PC | | | | Profile and High Profile are almost the same. If you |
