Subtitles don't appear on my TV

Hi you all,

Strange thing. I have a Nvidia Graphics card. If I put my card in clone mode and play my video in Full Screen on TV using overlay mode my subtitles don't appear on the TV. But the subtitles are visible on my computer.

I allready tried different settings but nothing works. Does anybody has a clue what to do. I have the latest version of BS player and codecs installed.

Regards,
Don
