we have a PC, a MAC and a PS3 at home and we have installed the PS3 Media Server on both our laptops. It works on both of them, however on the MAC it won't play the MKV files - we get a corrupted data message. If we access the very same files from the Windows PC, it plays with no problem. Is there something I can do about the MAC? Notice that the MAC per se plays the MKVs just fine.
