I'm playing a video in VLC which has dual audio tracks. It runs fine with one track (Language), but when I change to the second audio track, doesn't play the audio and gives the error below:

"No suitable decoder module: VLC does not support the audio or video format "undf". Unfortunately there is no way for you to fix this."

How do I fix this VLC Media Player error?

It says that there is no audio there basically. Which VLC do you use? Does the movie plays with other soundtrack in an other player like mpc-hc(from CCCP pack) ?

If yes, you can try a fresh VLC build like 1.1.0-pre5 or something (or pre4.. if I remember clearly they are at pre5 already).

I'm using VLC Media player 1.0.5 Goldeneye. – metal gear solid May 22 '10 at 15:14
Then do what I said, try it with other players for example, or a fresh vlc build. – Shiki May 22 '10 at 15:28
Still same problem with latest build – metal gear solid May 23 '10 at 4:59
Thanks - Now it's working fine in K-Lite Codec Pack 5.9.0 FULL – metal gear solid May 23 '10 at 6:02
People say you should stay away from that. (Not me, I never really used it. Try , or kmplayer. Well.. if it works..^^") – Shiki May 23 '10 at 6:34
