What do you mean by "is not indexing"?
Are you able to successfully "burn" your DVD to a folder on your hard drive?
On what computer operating system is your Premiere Elements 11 running?
Please explain your situation "it is not indexing". Where do you see this message
a. in the progress bar at the bottom right of the workspace when you try to import the file(s) into the project
b. is it a pop up during the burn to process...if so, what exactly is going on with Publish+Share/Disc/ when it first appears?
Where are your source media for the project stored? Where are your project's Scratch Disk pointed and how much free hard drive space is at those locations. See Edit Menu/Preferences/Scratch Disks and especially the Disk Encoding category.
Please confirm your burn to:
a. NTSC or PAL ----DVD-VIDEO standard or widescreen on DVD disc
b. NTSC or PAL ----AVCHD on DVD disc
c. NTSC or PAL ----Blu-ray disk format on Blu-ray disk?
Any questions or need clarification on the above, please ask.
