This MPEG-2 Codec will allow you to open MPEG-2 files in TMPGEnc and in MS Media Player -- plus a host of other programs Please note I did not WRITE this codec Please do not ask me any video specific questions. If you can open MPEG-2 files then it installed correctly ... any questions beyond that I can't answer! The installer can be used in command line mode also. mpeg-2 /s thats the "silent install" If the MPEG-2 Codec Installer doesn't run then you need the VB6 Runtime DLL's http://www.softwarepatch.com/windows/vbrun6download.htm contact stinky@dosrules.com with any problems related to the installer only!
