Hi,

Thank u markfm for your Answer.

But Microsoft Video 1 is not WMV 1. Microsoft Video 1 is an old Microsoft codec.

Do u know any Method to convert the AVI File from Microsoft Video 1 to a Codec that vlc supports?

My mistake -- you're talking old stuff. Go for a file conversion -- try a Google search for:
convert "microsoft video 1"
