Windows Audio compression

Hi. I need help with WM1 audio codec. I tried to open an ASF video with VirtualDub 1.3 and got this error:

“Couldn’t locate decompressor for format ‘WMV1’ (unknown)”

The video plays fine in Media Player with audio. I have Nimo and Windows Media Encode package installed.

What should I do for this?

This is a known problem with some ASF files.

There may be a workaround, but it isn’t easy and is a work in progress.

For one user’s experiments with this problem, see wmv1 codec thing.
