Ok, you’re burning to dvd not cd. That is a different subject.
And since you are using a converter, I’d guess you are starting with either an avi file or a mp4 file.
Try converting with DVDFlick or FAVC to go to dvd video format. Burn to disk with ImgBurn. Use good media like Verbatim 16x disks and burn at 8x or 12x speed, depending on your burner. If you are using a laptop drive, burn at 8x.
Of course I’m just guessing here at what you are starting with and your intended output. Let me know if you are trying to do something different.
