Hi everyone!

There's a problem with avi file exported by the game. The index was broken during the export. I was trying to conver the video to another format using Virtual Dub but got no audio. VLC, MeGui, ffmpeg, Handbrake say there's an empty audio stream, AviDemux can't open the file at all. But MediaInfo say the audio track is present in the file.

Maybe somebody knows... Is there any software which can extract audio data from corrupted AVI?
I tried to search through the forum but it seems the search panel doesn't work for me
