Getting A/V sync values right

Instead of using the try and error remux approch, prior to remuxing, you could use Media Player Classic to determine the correct audio delay value and then use the value in VDM or DivXMuxGUI for the actual muxing. Much quicker than a dozen remux tests.

Now restart MPC, open your video and play it. To correct the A/V sync simply select View-> Options from the menu again and try differnet values until your video is in sync. Then use the value you found for remuxing
