How do I know if I have the latest update to RP?

When checking for an update there a 2 small files "Producer SDK for Real Aduio Lossless" & "Real Audio 2.0 Codec Plug-in.

I have had trouble burning DVD's & version v.18.1.11.204 supposedly has solved the issue. I am tired of wasting DVD's only to find the problems are not fixed.
