>I have built a DVD a while ago and I have the files on my PC. That is the regular AUDIO_TS, ULEADDF and VIDEO_TS directory structure with the .mpg sound file at the root. Windows Media Player cannot play that. Obviously, a software needs to be installed in order for that to play on Windows. Any recommandations?

I use VLC for playing practically anything. You can get it from http://www.videolan.org/ and it plays a huge range of file formats as well as CDs, DVDs and Bluray disks.
