Part 1. What is a VRO file?
A DVD-VR recorded disc contains a 'DVD_RTAV' directory in the root of the filesystem, in which a single 'VR_MOVIE.VRO' file exists, containing the raw audio and video data for all video recordings on the disc. The recording metadata along with navigation data to represent playlist,programs and so on are also stored in the 'VR_MANGR.IFO' file in the same directory. A backup copy of this file (VR_MANGR.BUP) typically is present as well.
Unlike standard DVD-Video recordings, the aspect ratio (4:3 or 16:9) is contained in the .VRO file itself as part of the video stream. Thus DVD-VR supports mixed format presentations within a single .VRO file. Contrast DVD-Video where the aspect ratio is coded into the accompanying .IFO file and thus a single .VOB file can be in a single aspect ratio only.
VRO is a container format for multiplexed audiovisual content. VRO file is an equivalent to a collection of DVD-Video VOB files. If one doesn't care about any edits (e.g., deleting of recorded videos), one can play the VRO directly as if it was a standard DVD-Video VOB file. Fragmented VRO files are not widely supported by software players and video editing software.
