My regards to the community, I am looking for software that can help me to convert my DVD into AVI and WMV formats. I have tried a few ones but that has been such a good experience. I need to get a one that has a good speed and also maintains the quality with its conversion.

Do drop in your views to help get me a better solution.  

Hello, my friend uses a one that has been providing good conversion with a maintained quality. He has not had any problems yet and is happy to use that. The DVD ripping software he uses comes with built-in video editing features. It can rip DVDs straight to a variety of compressed video file formats such as AVI, WMV, DivX, Xvid, 3GP, MP4, H.264, RM, MOV, SWF, FLV, VOB and even M4V.

Hope this will be useful to you.
