simple adjustment to uncompressing the MSS package

[Todd_Christ]

Maybe trivial for some, but I was scratching my head as I followed the directions implicitly... 

$ tar -xvzf MediaServerStudio*.tar.gz
$ cd MediaServerStudio*
$ tar -xvzf SDK*.tar.gz
$ cd SDK*

you need to cd SLES or CentOS directory depending on your build, in order to decompress the install scripts in the next step

$ tar -xvzf install_scripts*.tar.gz

Thanks Todd. Will make the modification to the install guides in the next release.
