[Jobert]

Hello good day guys;

I want to ask help bout this problem. I successfully
downloaded a movie which is .avi in format den to be
able to burn it on vcd/svcd it should be mpeg in
format. The i convert the avi to mpeg using ffmpeg.
Then my prob is when finishing converting the avi to
mpeg i use k3b to burn in as vcd then it always have
this problem.
