WARNING! Apparently this tool will only work properly for files less than 4GB in size. deoxymoron noted an audio problem "near the end of the file";apparently the problem is a 4GB file size problem. Following the 4GB mark (approximately 18:52 at full D1 resolution for me) the audio turns to hash (a loud hiss). This happens with no warning or errors generated, so you will think all is OK. If you only listen to the first few minutes of the converted AVI, you will think all is OK.

If you are working with small files, it works fine, but be warned! This bit me on several large captures.
