cannot import audio from vifeo file in nuendo

[ARCADIOS]

i always get this message:
"cannot import these audio streams"
what can i do?
everybody says that it is easy, for example to import avi file and extract the audio as well.
in case there is no solution, i have to get a video to audio converter.
but nuendo should do this.
is it a conflict between my ati graph card and scopes cards?

Cards shouldn't be involved at all, it's a codec-format thing or a limitation of Nuendo, check at Nuendo forums better.
