I am attempting to play a video that is in an unusual file format; it's burned onto a disc and there are several file formats, but the main file appears to have the extension ".dat"


When I attempt to play it on VLC media player, the following error message pops up


"No suitable decoder module

VLC does not support the audio or video format "undf".

Unfortunately there is no way for you to fix this."


I know "undf" means "unidentified."


I need to be able to review this file for work.


Is there a safe program that folks would recommend?  I did some research and there were a few recommended players that MIGHT be able to play such a file, but they appeared to be adware.


What can I do to get this DVD file to play?


Wise ones, what sayeth you?
