So, it is a bug from CoreAVC codec, with AVCHD Canon HFxx video files. They are trying to solve it.
Using the H264 Cyberlink or FFdshow codec could be an alternative.
I have same issues of audio out of sync with .m2ts, however, when I play it with MPC-HC (standalone) it is fine.
BUT, when I play with MPC-HC as external player through media portal, it is again out of sync!!?? How is it possible?
Second question: is there a way to scale movie to 16:9 in mediaportal? The stretch or non-linear stretch do not stretch 1080p material to full screen as I would like to (fullHD plasma screen).
Specs: Nvidia 8200, AMD 4850dual core, 4GB RAM + Vista ultimate, CoreAVC, Haali splitter and MPC-HC as part of CCCP.
