View Full Version : "Class not registered" when playing MPEG-2 in WMP

I have searched and tried many different things but recently Windows Media Player started giving me a message saying "Class not registered" whenever I try playing MPEG-2 files (SVCD or DVD) that I created with CCE. I also tried upgrading to WMP 9 beta and still have the same problem. Of course there is no info on MS help page on this.

I realize that this is a codec problem but I have tried many things. I uninstalled/installed PowerVCRII/PowerDVD and the Indeo software that comes with it. I also have uninstalled/reinstalled the latest Nimo codec pack. The files won't even play in PowerDVD.

I know that the files are not corrupt because I used to be able to play them. I don't know what I installed that messed everything up but any help would be greatly appreciated!

I am currently running Windows XP if that makes a difference on this issue. Right now I'm thinking my only possible solution is a clean install.

As far as I know, WMP can't play SVCD MPEGs. If I'm wrong, I'd like to know how you achieved this. Anyway, I always use the free player called STHSDVD, which has DVD, SVCD abd VCD support.

Windows Media Player can play the MPEG-2 file as long as you have an MPEG-2 filter. I cannot play the SVCD disc though. The problem was quite interesting. Installing PowerDVD should have installed a MPEG-2 filter that would have allowed WMP to play the file. I downloaded a free standalone filter from this link MPEG2Codec Installer (http://www.dvd-digest.tv/downloads/files/encode/mpeg2codec_installer.zip) and installed it. The first time through the install it gave me an error and said that the filter was already installed. I uninstalled it from the tool and re-installed and everything worked fine.

I was able to replicate the problem. It seems as though something got locked up while I was installing software. I had installed the latest Nimo and the latest DVD2SVCD. There are different versions of the same software in these packages.

I'm glad I was able to sort through this problem and hopefully this solution will help anyone else having a similar one.

Get rid off that shitty nimo-pack!

"Class not registered" is not an errormessage of WMP. That lame nimo-codec pack caused so many problems so far. Uninstall it and get the codecs one by one. For mpeg2-playback you just need the fraunhofer mpeg2-codecs available on doom9's download page.
