Using TMT with MyFilms to play regular DVDs (3 Viewers)

[gamestar]

I'm not sure if this is a MyFilms question or a general MediaPortal question but I'm trying to use TotalMedia Theater to play regular DVDs. I checked the use external player option in MediaPortal but when I select a movie it uses the internal player. I've had this working with other external players. I swear I remember seeing a thread a while back where somebody was using several parameters with TMT but I can't find it again. Anybody have an idea?

Thanks
