Hi all. I am a n00b seeking assistance. I recently came across a backup of a DVD containing the following file formats: .VSI, .XVO, and .IFO. I have never seen this before. I am accustomed to seeing .BUP, .VOB, and .IFO. I am unable to view the aforementioned DVD backup using any of the video players currently installed on my computer, and a Google search yielded no results (at least none in a language I could interpret). Has anybody run across a backup using these file formats before? If so, can you recommend a player to open the backup? Or a program to burn the backup? Any help in the matter will be greatly appreciated.
