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 . file can be in a single aspect ratio only.
for multiplexed audiovisual content. VRO file is an equivalent to a collection of DVD-Video VOB files. If one doesn't care about edits (e.g., deleting recorded videos), one can play the VRO directly as if it were a standard DVD-Video VOB file.
