can't compress audio in vdub

[Shaorin]

When I loaded this video file in virtualdub I get this error http://i52.photobucket.com/albums/g13/chibi-pucca/vduberror.gif
then when I try to compress the audio it won't let me cause it came with a error showing this http://i52.photobucket.com/albums/g13/chibi-pucca/vduberror2.gif but I already have the codecs installed.

This is info about the video shown in gspot http://i52.photobucket.com/albums/g13/chibi-pucca/gspot1.gif

Forget compression , set audio to full processing , then compression to none , save out as wav .

Then under audio , sellect wav , locate the wav file just created , and now compression can take place .

Failing that , give super a crack at it , its worked well on problematic clips .
