help with MTS.

I carn't seem to get MTS to work on my mac or my windows laptop. I get the sound on the windows laptop but just a black screen. On the Mac i get nothing and a white screen comes up. Anyone have ideas why this could be? certain apps or settings?

cheers. rhid.

what are the specs on your mac? what browser are you using? I watch MTS without lag or flaw on my macbook.
