Can't play cd of daughters ceremony

I get the following message "In order for RealOne Player to play MPEG-2 files, you must first install a DirectShow-compatible MPEG-2 decoder on your computer. Most computer DVD playback software includes a DirectShow-compatible MPEG-2 decoder. If you have DVD playback software installed, please try re-installing this software before attempting to playback MPEG-2 content. " when I try to play a recorded MPG of a cermony my daughter held. It was converted from HDVCR to a cd. The CD will play on my machine but not hers on either Winmedia ( or as above Realmedia 10. I have downloaded the codec for the update to winmedia. Not sure what is being asked for here. Could someone please advise me what I need and where I might donload it. Preferably free.
Thanks in advance.

 

You need a proper mpeg-2 codec.
Typically, these only come with purchased versions of WinDVD, PowerDVD, and other GOOD software players. Not WMP, or DivX, etc.
Look in the tools section at www.videohelp.com for mpeg-2. I think there might be one free one left.
