To function properly, TPlayer requires the following software properly installed:
 

 Microsoft Windows (tested on 98SE, Me and XP but should run fine on 95/98 and 2000 also)
 Microsoft DirectX 8.x
 Windows Media Player or Fraunhofer IIS MPEG Layer-3 Codec (L3CODECA.ACM)
    (Note: WMP is not necessary if you have the file L3CODECA.ACM installed)
 At least one sound card. Two sound cards supported for monitor speakers output.
 Screen resolution 800x600 minimum, 16/24/32bit color

DirectX for Windows 98/Me/2000.
DirectX for Windows 95.

 For ogg Vorbis support, you need the DirectShow Filters by Tobias 

 If you have an old version of Xing Player and have problem running TPlayer because of ASMAUDDECFF.DLL and XMP3DEC.DLL errors, just rename those two files and things should be ok.
