Thread: Windows DVD not recognised?

I have been given a DVD (-R) to copy and edit**
When I put it in my Stand alone DVD player or PS3 the media plays fine.
However when I try to look at the files on the disk in order to copy the .vob to my editing software there are either no files there (not even hidden ones), a message says windows cannot recognise the files on this disk, or the whole DVD drive locks up or becomes unnavailable.
Have tried 4 different PCs and 5 different DVD drives.
Can anyone help?

Having just trawled the internet it seems that My Windows XP is seing the Disc as a RAW file system. And therefore does not recognise the files on it.
Any ideas how I can see, copy, change the files so that Windows can see and copy or convert them?
