mpeg audio video sync problems

When I play a mpeg that i created using tpmgenc the audio and video is out of sync on bsplayer. I have the klite codecs installed in my computer. When i play the same file on the windows media classic player or on powerdvd it plays perfectly. I have been messing around with codecs and settings but can't seem t o get anything to fix it. If someone could help I would really appreciate it.
