Did you ensure that the Fit Contents to Avaiable Space option was checked on the DVD burn screen?
What model of camcorder is your video coming from and what format and resolution is it? Did you use Premiere Elements to get the video from the camcorder to your computer?
What project settings are you using? (You can see but not change them under Edit/Project Settings)
I've tried both options - Fit Contents to Available Space both checked and unchecked. I've also tried selecting burn to folder - both the 4.7 and 8.5 GB Folder. Setting s as follows:
The Capture Format is DV. Video render is set for Optimize Stills. The camcorder is a Sony Handycam DCR-SR82 Hard Disk Drive, set for HQ quality of recorded video. I used the Adobe Video Importer to import the video into the project. Even buring the 1 hour version of the project leaves plenty of unburned space on the DVD itself (from appearances). Seems odd that anything over 1 hour seems to compile correctly, yet when it goes to burn, it starts the process, goes to 26%, then jumps to the end and says complete, yet the burner doesn't light up, and there is no file. I thought my burner might have been the issue, but does the same thing when burning to folder.
Perhaps it would have been better if you started your own new thread on the specifics of your situation.
But lots of questions.
1. On what computer operating system are you running Premiere Elements 7 and 10?
2. When you say for version 10 "will not write to DVD or to a folder", where are you blocked...
a. burner is not recognized in burn dialog
b. transcoding errors
c. device errors
d. disc not recognized
e. goes to 99% and then nothing
In the case of burn to folder, everything above except a, c, and d
Do you have Nero or any other burn software installed on this computer? And, the old question "Is your computer optimized?" I ask this in spite of the fact that you do state that Premiere Elements 7 burn to DVD is working on the same computer. What are we looking at in terms of computer resources?
Have you reviewed the Adobe document on burn to disc troubleshooting?
