Nero Digital MP4 files with diff icons

I have some Nero Digital MP4 files encoded with earlier versions of Recode (a couple of months back). They have a “Showtime” yellow icon attached to them.

More recent versions of recode are producing MP4 files with a different icon (a Nero Digital logo icon). They also have a separate Nero Digital properties page attached to the file (which the earlier files do not).

My question is: How do I get the earlier files into the newer format?

Thank you

I actually lost these Icons reinstalling Nero and I am searching on how to get them back myself.
