RealPlayer upgrade(rv9)doesn,t work.
 

I have downloaded rv9 and copied codecs in to usr/lib/RealPlayer8/Codecs(x11 virsion)
and it,s not working. (mandrake9.1+realplayer8rpm)

am i right in thinking you have downloaded realone and uncompressed it and just overwritten half of the files from rp8? no wonder it won't work... remove the entire old very, preferably by rpm itself, and then install the new one correctly.

I did not have find realone player for linux at real.com .instead ,I have found rv9 upgrade package for realplayer8. rv9 came with read me which says copy /codecs/ to /real/codecs/.

I wish I could remember where I found it, but there was a good RealPlayer RPM that I wound up using. It was an ad-free RealPlayer8 source rpm that updated itself automatically when I tried playing newer Real Media content. I wish I could remember the details, but you might try searching around for it.

Have you considered enlisting Wine to solve your problem?
