My problem is not a new one: when splitting DivX files, the second portion of the file has no sound. I have done the keyframes, direct stream copy and all the normal procedures, but nothing works. However, i found this in general: When checking the original DivX file information with VirtualDub, the information under audio stream is not complete. In fact, it says there "indeterminate". Anyone know how to work out this problem? help is appreciated.
