Can someone explain "VR" vs. "Video" DVD recording modes? Can any on-board editing be done with a "Video" mode recording? It seems like a "VR" mode recording is much more flexible.

However, can any non-Toshiba players play a "VR" mode disk? And if put in a computer, can the underlying VOB, etc. files be accessed?

VR mode, usually to a DVD-R/-RW disc, allows for special editing features, such as edit while viewing, etc, but can only be viewed on a player that supports those discs. 'Video' mode , on +R/RW or -R/RW discs should be viewable on any DVD player that will play those disc, including computers, laptops, portables, etc.

VR mode
From Wikipedia, the free encyclopedia

VR mode or Video Recording mode is a feature on stand-alone consumer and computer DVD recorders that allows video recording and editing on a DVD rewritable disc.

In VR mode, users can create and rename titles for the scenes. Also, if a scene is deleted, the space allocated by it will be utilized later without the need of reformatting a disc.

If the user would like to record on the same disc again at a later time, in VR mode, users may eject the disc and it will not be finalized by the recorder until it is manually initiated. For the sake of comparison, any DVD recorded in VR's competitor V mode (or Video mode) will be automatically finalized before it is ejected by the recorder. Disc finalization is still required if the disc formatted for VR mode will be played in another DVD player.

Currently, users can only record in VR mode with the use of DVD-RW, DVD-RAM and DVD+RW discs, (updated in 2000 to accommodate DVD-R (General)) [DVD players marked "RW compatible" and "DVD Multi" can play DVD-VR recorded discs] and on some recorders, also on hard-disk drives.

Blu-ray Disc and HD DVD also support VR mode-like features.

A very common question I receive from owners of DVD recorders and persons considering a DVD recorder purchase is: "How much time can I record on a DVD?" This answer to this question for each DVD recorder is explained in both the published specifications (which are available online) and the user manual for that DVD recorder.

However, for those that are still in the purchasing consideration stage, here is an overview of the recording times available on a standard 4.7 GB blank DVD and how these recording times are labeled. These times are for single layer, single sided discs. For double-layer, or double sided discs, multiply each time by two:

XP - 1 Hour

SP - 2 Hours

LP - 4 Hours

EP - 6 Hours

SLP - 8 Hours

SEP - 10 Hours

In addition, some DVD recorders also feature HSP (1.5 hours), LSP (2.5 hours), and ESP (3 hours).

Also, keep in mind, just as with VCR recordings, the less recording time you use to fill the disc the better the quality and compatibility with playback on other DVD players.

XP, HSP, SP are the most compatible and provide what is considered standard DVD quality (depending on the quality of the source material)

LSP and LP would be the next best choice - which should still be compatible with playback on most DVD players at fair quality - you may experience some minor stalls or skips.

The remaining record modes should be avoided, if possible, as the video compression needed to place this much time on a disc will cause many more digital artifacts and will affect play compatibility on other DVD players - Also, the video quality would be very poor - about the same or worse than the VHS EP/SLP modes.

Thanks!

Now what happens if you make a VR disc and then finalize it? Does that make it compatible with all/most players? Or will it still only work on players that support VR?
