I'm an average pc user, and I'm having a bit of trouble with some of the instructions for installing real alternatives:

1. Unarchive the package and use the files from Release folder if you're running Windows 9x/Me or Release Unicode if you're running Windows 2000/XP.

2. Copy DLL or AX files in system32 folder [ C:\WINDOWS\system32 ]

3. Then launch command prompt [ START > Run > Type: cmd ]

• To install the files, type: regsvr32 filename.dll or regsvr32 filename.ax
• To uninstall the files, use: regsvr32 -u filename.dll or regsvr32 -u filename.ax

4. In the end, you should receive a message saying that your file was succesfully installed/uninstalled.

My problems:
#1- how do I "release" unicode running windows xp?
#2- how do I copy AX files to system 32 folder exactly?
The rest I think I can manage-
Thanks for any help

Well, you'll have a folder 'Release Unicode' after unzipping this archive and a file "RealMediaSplitter.ax" in it. Just simply copy this file (using Windows Explorer) to the SYSTEM32 directory.
Then use the command line prompt.

Or you can download RadLight Filter Manager.
Unzip.
Launch.
You'll find RealMedia Splitter under DirectShow Filters.
Highlight it, click 'Register'.
Browse for the RealMediaSplitter.ax
DONE (?)
