I found the answer from another forum member!
And my AVI file loads both tracks now!
Vegas even loaded a .swf 🙂

It is a free download.

Combined Community Codec Pack

“I have CCCP installed, always had it. this one is used by many people, it is a standard. i just left it in default”

Hope this helps others.

Sincerely,
Crystal
