It depends a bit what goes wrong. You say the burning? If the actual production of the DVD goes right, you may want to decide to create the DVD and not burn it and use separate DVD burning software to make the DVD?
If the DVD creation process goes wrong, then the focus is perhaps on the correct settings for the creation? Have you selected 2D disk (Which I guess you want), and within that DVD with either 4.7GB or 8.5GB. Have you looked at the video and audio settings? Are they correct? The selection for NTCS or PAL (in the preferences). Etc.
And … since I don’t know what precisely goes wrong, did you try the preview to see whether it works?
I agree with you that before you know it, see all parameters, you need to know a bit more to get them doing what you want.
