Yes, I did have problems getting the Neo to learn seveal buttons off the 950's remote. The work around was to use pronto2neo converter and NeoHacker. Both can be found on remotecentral.com.
No, I have not had a chance to make a full .ncf file for the 950, but when I do it will be uploaded. I create the buttons as I need them. Keep my e-mail, and if you do decide to get the Neo I will be more than happy to e-mail you the .ncf I do have.
