(Note to Windows 64 bit users: most codecs are not available in 64 bit versions, and some common codecs like Indeo5 are not available for Windows 7 at all; however it is reported that R2011b will have a new class that will relieve some of the codec issues.)

Can you advise a suitable converter AVI with matlab
That's the MPEG-1 Layer 3 MP3 audio codec, but it appears that it is most often generated by Unix software that produces incorrect audio headers when encoding.
Try the codec at http://www.moviecodec.com/download-audio-codecs/mpeg-1-layer-3-codec-18/
