DVD_RTAV, DV mode -RV, mac OSX

[anp]

I have a DVD_RTAV folder with the .VRO file (+ the other 2) inside.
This came from a DVD my sister made with her sony dvd recorder thing
What software on a mac can I use to play this video without converting it to another form?
the dvd player that came with my OSX won't do it.

Also, what software can I use to extract the video

I have used ffmpegX before, and it seems to work with the .VRO file.
However, the only format it will successfully convert it to is DV. This is not a problem for me, BUT it makes every file 5X the size (my 200 MB .VRO turns into 1 GB DV file)
Is there a way to convert it to a form that basically doesn't change the quality or size of the file?

I simply want to watch the video before I even know if I want to burn it to a DVD for myself

Thanks

You might get better help in our mac forum section so I'm moving you. And welcome to our forum!

Toast's media browser can extract from .VRO to .MPG.
Also, have you tried playing the .VRO files (copied to your hard drive) with VLC?
