File with a .VRO extension contains audio and video recording stored in real-time on a DVD with stream data transfer. It is related to the IFO metadata file which contains information on data’s location. Sometimes it may be read by applications after changing the extension into .MPG, because it uses similar coding. VRO files are used by video DVD recorders and some cameras with mini-DVD. The VRO format can be converted into more popular formats, for instance VOB or MP4, if proper recording software is used, such as AVS Video Tools VRO Converter or Wondershare Video Converter, or on-line tools, for instance - media.io
