Sound problems after decoding

Hi all, Im having some trouble when decoding some of my movie files. I have SHARK TALE.avi (for example), which plays fine in my mplayer as i have codecs installed but when i run it through TMPGEnc3xp it manages to convert the video file to DVD format, but there is no sound :frowning: . I have used Gspot on the .avi and it confirms tht all codecs are installed and it should convert perfectly… but it doesnt!!! :a

Please help, anyone, as I have other files doin the same thing and it very frustrating. Thanks :rolleyes:
