What is an XVO File?

A file with the XVO file extension is a ratDVD Internal video file used by the RatDVD DVD ripping software.

A number of files normally accompany XVO files too - like XML, IFO, and VSI files, all of which are contained in an AV_TS folder and then ZIP-compressed to a format that the RatDVD software can recognize.

How To Open an XVO File

XVO files are the actual video files that make up a .RATDVD file. When XVO files are contained within this .RATDVD format, the RatDVD software decompresses the RATDVD file to use its contents for building a DVD.

So, just to be clear, the XVO files themselves don't actually open in the RatDVD program unless they exist in the .RATDVD file format...

To use XVO files with RatDVD, you must compress the AV_TS folder (the one that contains the XVO and other files) and Version.XML file together (the XML file should exist outside the AV_TS folder) with ZIP compression, and then rename the .ZIP file to a .RATDVD file.

Note: You can use a free file zip/unzip program (like 7-Zip) to create a ZIP file, but just be sure that the compression level is set to "none" so that the data is just stored in a .ZIP file and not actually compressed.

How To Convert an XVO File

While an XVO file is a video file, it can't be converted by most free file converters because it's only part of an extracted .RATDVD file. There's no real need to convert just the XVO file to something else.

Instead, once you've used the method described above to create the .RATDVD file out of your XVO files, you can use the RatDVD software to convert the .RATDVD file back to DVD format (see this tutorial).

Then, you should be able to use a free video converter to convert the resulting VOB files to a file format you're more familiar with, like MP4, MKV, ISO, etc.
