You can try this solution, although it is far from ideal.
Find software application called DVD-Movie Album SE. It was written by Panasonic, but it should be compatible with most DVD-RAM optical drives.
I’m not sure how it would read VROs burned from a Toshiba DVD recorder, but assuming there are no problems, within the application there’s an “Export Video to hard drive” option. The resulting files may not retain their original characteristics (i.e. aspect ratio, bitrate, etc), but at least you could play it from your hard drive and manipulate it as you wish to from there.
