I got my Vista to a least see the VR mode files in ISOBuster. The trial version is limited function .I didn't want to buy the program so I can't say for sure but it indicated it would extract the VR mode files.
I also tried the ISOPuzzle it looked like it was trying to copy the VR mode disc to the HD but I gave up after 20 hours on one disc .
Dogg may be on the right track but I tried a couple of the UDF reader freeware the Nero INCD & Roxio Adaptec ones & no luck there .Maybe I just need a good tutorial or guide.
Now for the funny thing my older computer that has Windows98se on it sees the disc with no problem & with VLC I can watch the disc on it.
So if you have access to a computer with 98 on it you might be able to open the disc copy the .vro file to a large flash drive or external HD.Then your newer OS can see the .vro file.
Then you may be able to rename it's file extension to .vob & name it
It.s not really a good .vob but it lets some software recognize it as one.I was able to take it from there & run it through several freeware programs.I ended up with a playable standard DVD format disc.
I'm sure there are pay for programs that might do it all with one program.
