Okay guys, I solved my problem. Thank you so much for your help.

Here is how I solved:

I checked this file (thanks KoMiKo), and I found that there are three buttons code missing in my registry. Keep in mind that each remote has its own codes, so find the right one.

For number 1, in the picture above, it's widescreen 0x81
For number 2 it's return 0x80
For number 3 it's photo 0x6F

So I simply added those codes to my registry file, and now I can see these buttons in "MCE Remote Mapper Tool". All the buttons are working now, and I can map or re-map them as I like.

I hope this will help others

Thank you
