You have to decompress the avi files. Virtualdub will do this for you; you open the file in vdub and save it with an uncompressed format. The only gotcha is that you have to save it under a different name; you can't save it as itself.

So you have two options:

1. Copy all the townnnn.avi files to townnnn-old.avi.
2. Open each of those files under vdub
3. Save the file as townnnn.avi

or...

1. Open each of townnnn.avi files under vdub
2. Save the file as townnnn-new.avi
3. Rename the old townnnn.avi file to townnnn-old.avi
4. Rename the townnnn-new.avi files to townnnn.avi
