I Guess i'll post it again....
UNDF isn’t a file format, but a short error code to explain that the file you are trying to play has an undefined file format. Basically, it means the VLC media player is not able to read the format of the file you are trying to play. When the VLC media is unable to recognize the file format, it would certainly throw an error such as “No suitable decoder module: VLC does not support the audio or video format undf”.
It's not VLC, It's the video file.
but can be fixed with the right codecs and the solution can be googled.
he just claims to be unable to find a solution as hes afraid to download things and try to resolve it.
