I don't think you'll find any codes as the Vizio remote uses a newer IR coding than the Denon.
However, you can replace both remotes with a Logitech Harmony Universal Remote!
The Harmony remotes work on several different IR coding schemes with many different types of devices.
If 1 remote is what you're after, the Harmony remotes are the best!
Mine has saved several devices for me because I could just download the latest IR codes from their website AND I can teach it the codes if I can't download them but still have the original remote for the device.
This is definitely the way to go, IMHO.

Hope this answers your question.

Entering a new remote code will automatically erase the existing code for the device it is currently operating.
The remote for Denon devices is 111.
