On the
Universal Disk Format talk page and on the helpdesk pages, people have asked for some more information on DVD+VR. That lead to this page being created. I tried to provide a broad overview of the standard and featuring based on public information and information one can determine in the blink of an eye using tools such as vobedit, ifoedit,
isobuster and the
udf file system verfier software. This page is still missing some information. Examples are recording modes (video quality), and recording capacity for HQ, SP, LP, EP, SLP and SEP. I had a hard time finding reliable public sources for details on these modes (this is, not being vendor or product-specific).

DVD+VR on DVD-R/RW discs
Some DVD recorders can record DVD+VR format on DVD-R/RW discs. An example is the Funai SV2000 WV10D6.
This is indeed technically possible. The DVD-VR and DVD+VR do not have the same relationship as DVD-RW and DVD+RW. However, although DVD-VR is perfectly recordable on DVD+RW discs with no problem, recording DVD+VR format on DVD-RW discs has a major limitation in that under certain conditions the recorder has to read and store the entire disc content, reformat and write the entire content back. This is because the DVD-RW system cannot seemlessly add extra video to the end of an existing .VOB file.

It has been claimed (by an unsourced claim) that a single .VOB file is used for all recordings. This cannot be correct as a .VOB file is limited to just 1Gb in size by the DVD-Video standard.

While this interpretation of the article text is close, it's not *quite* correct. What the article actually says is "a single VOB set is shared by all recordings." This means that the DVD recorder stores all recordings as a single set of split VOB files, not a single VOB file by itself. However, I don't know if this behavior is specified as part of the standard, or simply an observed effect of the lazy implementations used by DVD recorders on the market.
