Hi,

DVD-VR and DVD+VR don?t offer less features than standard DVD-Video
discs. Instead, they offer more:

?In short, DVD VR is a format that enables you to produce a DVD movie
that can be edited. A DVD produced in VR format will allow you to add
new video contents, change menu backgrounds, insert chapters, split
video clips and even remove unwanted video segments (as long as you
have enough space available on the disc). And as more DVD authoring
applications are adopting the new VR standard, like CyberLink's
PowerProducer 2, you will be able to easily record, edit, and playback
your DVD movie creations.?

This means that you will be able to create menu?s, use the same high
resolution video, use chapters, multiple audio languages, multiple
subtitles etc. on a DVD-VR or DVD+VR disc.
At the same time, you will have a lot more editing options than you
will have with a standard DVD-Video disc.

However, there is one important limitation to DVD-VR and DVD+VR discs:
they are a lot less compatible with standard DVD Video players.

?I quickly found a major problem with recording to the VR format--lack
of compatibility. Even after finalizing, the disc will not play in a
standard DVD player (one that doesn't record). So I couldn't watch it
on the DVD player in the other room. So I switched the default to
DVD-Video, which creates a DVD (after it's finalized) in the standard
DVD format.?

?Well, as PhilipL stated earlier, there are currently a limited number
of standalone DVD players from Panasonic and Pioneer, which are able
to play the DVD-VR recorded discs.?

What you simply can do, I create a DVD-VR or DVD+VR disc, and then
later convert it to a standard DVD-Video disc (when you want to be
able to play it on another player). There are multiple software
programs available which can easily perform this conversion.

Google: ?DVD-VR? OR ?DVD+VR? features

I hope you have enough information. If you need any more, please ask
for a clarification!

I didn't find in the link you gave me any mention of supporting
sorround sound with VR.
I am troubled by that because I even found one site that promoted some
DVD Recorder using DVD+VR and in the specification is was only stereo
sound.
I also didn't find a strict proof that it supports multiple subtitles.
about the other issues it seems fine.
seem like you need to dig some more , I also started in google using
"DVD-VR features " before i went to "Google Answers".

Hi,
I am sorry if my answer wasn't clear enough.
Anyway, what I was trying to say is that the only difference between a
normal DVD-Video disc and DVD+VR or DVD-VR disc, is the file system.
This means the contents of both systems can be exactly the same. You
only need a player which can handle the VR file system.

As for proof, the reason I can't point you to a website which
litteraly states that VR discs can have surround sound and/or multiple
subtitles is because it's basically a non-issue. It is not a problem.

If a program or DVD recorder states that it can only create DVD-VR
discs with stereo sound, it has nothing to do with the VR format. It
only means that that particular program or recorder, is not able to
create surround VR discs. Usually, these programs or recorders can't
record in surround mode at all (as this is quite a rare feature; only
the most modern programs allow for DVD Video recording with surround
sound).

Maybe I can give you another form of proof: multiple times I have
copied a standard DVD-Video disc (with surround sound and multiple
subtitles) and have used bits of it in DVD-VR format (while retaining
the surround sound).

I hope you have enough information. If there is anything else, please let me know. 

Thank you,

The clarification covered the missing parts.
even though no formal proof for the claims like some official web site
given, I am convinced by the personal experience of the researcher in
the subject.
