I found an MPEG2 Codec pack for WinXP so they would play in WMP9 and it works. But everytime i play a MPEG2 file the Desktop/Systray crash and comeback. It came with a Install.bat file and the 3 files below. How can i unregister those files so i can delete those files safely. Or can i just delete and be done with it? Code: install all four files in c:/windows/system doublw click on install.bat this will allow u to watch svcd in media player!!
