Alright, I really need some help here, this is annoying me.

I made a 77 min mpeg1 video file from a dvd of a movie using TMPGEnc 2.57 and its standard VideoCD settings for the region of the DVD. The file is approximately 770 MB. On every single guide on this site its says that I can store 800 MB on an 80 min vcd. But when I go to burn the VCD using VCDEasy it tells me the image created is 88 min therefore I cannot burn this 77 min mpeg1 as vcd. If I select overburn it burns but it doesn't burn properly, there is an error because the image length is 88 min. I am wondering why the image length isn't 77 min because when I put the failed vcd into my dvd player, it plays, but it displays that the vcd goes up to 82 min. That cannot be possible because the soure mpeg1 is only 77 min. Can anyone help me here?

One more fact: I've also used Nero to do this, same image lenght, can someone explain.

Thanks A Lot!
