What ho one and all,

Have quite a few mp4 videos of tv shows, downloaded from various sites.

When I play them, usually with MPC-HC, the lip sych gradually goes out of sync. Sometimes, it even starts out of sync. I don't understand how or why, since presumably the audio is part of the whole file.

Apart from manually advancing or retarding as I go, is there a way to lock the two together?

Toodle pip and thanks

Rex
