River Past DVD QuickRip does one simple thing - rip DVD into individual VOB files based on chapters. On a DVD-Video disc, the VOB files are not based on video clips. Each VOB may contain multiple videos, or one vidoe may span over several VOB files. This cases a problem for file-based video and audio converter and editor software because they will only read the first clip (chapter) in a VOB file. DVD QuickRip will rip the disc to individual VOB files based on chapters. You can easily use the ripped VOB files in a converter software to change to other formats, or even in some MPEG editing software. Use it in conjunction with River Past Crazi Video software to convert to iPod, PSP, PMC, or Zen Vision. No adware or spyware. DirectX 8 and Windows Media Format 9 required (download link available on the web site). Compatible with Windows Vista. 30 day MONEY BACK GUARANTEE
