As I dig into this sync problem with MF4, I find that it suffers from
the same problems as other applications.

When you capture your video, your audio and video information contains
time code tags which keep the playback in sync. When a program is
authored to DVD, these time code tags are removed by the authoring
tool and potential sync corrections are lost. VideoReDo automatically
processes files so that when these tags are removed the resulting
audio and video streams stay in sync. No matter what the original
source.
Why do I need frame accurate editing? Because if you don't have frame
accurate editing, you will not be able to specify the exact cut points
resulting in a very chopped looking edit.You will either remove wanted
program material, or leave in parts you did not want.
Frames in an MPEG compressed video are not stored sequentially and
most frames are stored simply as changes from some prior frame.
Without VideoReDo's special capabilities, the only place you can cut
safely is on a GOP boundary. A GOP boundary is where MPEG has encoded
a complete frame. Depending upon your source material, GOP boundaries
occur every 1/2 to 4 seconds.
