My MPEG-2 files play fine on my system and 3 others I own (2 Me & 2 Win2K), however, on some other systems, the Windows Media Player cannot locate a codec that will allow the files to be played. These other systems are 98's and Me's running Media Player 7.0. Is there a site where I can download the necessary codec's? I don't understand how all of my diverse systems seem to have the necessary codec's while these others don't.
