Use a DVD ripper
If you wish to make an .avi file from a DVD, you can use a DVD Ripper application. There are several such applications to choose from. For a list of DVD Ripper applications and links, go here: http://en.wikipedia.org/wiki/DVD_ripper
There is a software call DVD to WMV Ripper. You can use to rip DVD formats to .wmv formats.
There are many converter programs that will convert a DVD to an MP4 file. Freewares like HandBrake and WinX DVD Ripper do a good job. The latter one handles copy protected DVDs. Or you can pay to get Aiseesoft DVD Ripper, Tipard DVD Ripper, the 4Media DVD Ripper, etc, which work too. Online video converting site like Clipconverter can convert videos to MP4, but no DVD. I have ever tried Pavtube BDMagic and it also performed well while keeping the original video quality.

It will not affect the DVD, the ripper just copies the dvd.
A DVD ripper will copy the contents of a DVD to the hardware disk of a computer. The DVD ripper can deactivate the copy protection on the DVD, and then simply copies the contents of the DVD.
No DVD ripper will erase data from a DVD.
