What's the best DVD to AVI for novices program?

Another Output Size possibility is Target Quality (in Percentage). If, for example, you keep your movies on your hard drive, or run an HTPC, or plan to burn them to DVD-R and not to CD-R, then the final file size may not be important to you. A Quality encode will give you even quality throughout the movie at your designated percentage. The default is 75%, which will give you very good quality (but for DivX6 default is 60%). Good quality percentages begin at about 67% (Quantizer 3). I don't think there's much point in going above about 80% because then you'll lose some of the benefits of MPEG4's compression abilities. That's up to you, though. But remember, if you use a Percentage output, you'll lose control over file size. A Quality Percentage rip won't be split. The horizontal width will always be input source width, unless you set a fixed/maximum/minimum width in the Advanced Settings. Note: "Target Quality" mode performs 1-pass encoding while "Target Size" performs 2-passes encoding. (1 pass can speed up encoding considerably, but its not two times faster as you may expect.)
