Getting EyeTV closed captions to appear in XBMC

I prefer XBMC to NitoTV, looks nicer, more features and much more stable. However, when I view files recorded initially with EyeTV that have closed captions in NitoTV I see the closed captions. They don’t appear in XBMC. Is there something I can set that will make them appear? I reviewed the XBMC site but didn’t find anything helpful. It seems to be on their ‘wish’ list for a future addition.

There is reference to MPlayer supporting Closed Captions. Is that what NitoTV is using? Can XBMC be pointed to Mplayer as well?
