Met de DirectShow-filter ffdshow kunnen DivX-, XviD-, WMV-, MPEG1- en MPEG2-bestanden worden afgespeeld. Het programma maakt gebruik van de libavcodec van het ffmpeg-project voor video-decompressie, de postprocessing-code van mplayer voor verbeterde visuele kwaliteit van low bitrate-bestanden, en is gebaseerd op de originele DirectShow-filter van XviD. Sinds kort is er een nieuwe officiële alphaversie uitgebracht die 2004-08-06 als versieaanduiding heeft meegekregen. De release notes zien er als volgt uit:
