What version of Premiere Elements are you using and on what computer operating system is it running?
1. Check Disc Menu
a. spacing on Timeline menu markers (markers essentially on top of one another...instead of a few frames apart)
b. button overlaps on the main and/or scene menu pages (usually seen with red frames around offending buttons)
2. Timeline Content Flaws
a. Expand the Timeline with the -+ slider above the Timeline. Hit the End key of the computer main keyboard. Does that
take the Timeline Indicator to the end of the last file on the Timeline? If not and the Timeline Indicator goes beyond the end of the Timeline content,
look for fragments which can be large or present as thin black vertical lines scattered in the tracks.
b. While the Timeline is expanded, look for other irregularities related to placement of transitions and titles and gaps.
3. Do you have a stop marker at the end of the last item on the Timeline? If so, please remove it since it is not needed and
causes problems at that location.
Are you producing a DVD-VIDEO on DVD disc or AVCHD format on DVD disc? When you have the disc in the burner tray,
what does the burn dialog Quality area show for Space Required and Bitrate with and without a check mark next to "Fit
Content to Available Space"?
Please review and consider and then we will decide what next based on your reply with details.
