It is certainly not looking for something until it is needed. In my case I needed DVD rip to have it on my computer every time I wanted, and found the solution in one of the best blogs I always visit: GHacks. The truth is an optimal solution.
It is Your Free DVD Ripper An excellent program (free) for Windows that under a clean interface and easy to use (as is witnessed in the screenshot above), allows you to convert your DVD movie or video to any video or audio format you want.
Your Free DVD Ripper allows you to rip (rip understood as moving from logical disk format, CD or DVD, a format system. For example: Video to MPEG, AVI, etc.; audio to MP3, WAV, etc.) your DVD to video (MPEG , AVI, DivX, VCD, SVCD) and audio (MP3, WAV) in its interface.
Best of Your Free DVD Ripper is that it lets you specify what to convert, which pieces, which tracks the DVD, what format, you can either convert the whole DVD or a piece of it, everything is ready to what you need. It is an excellent tool.
