What model of camcorder is your original footage coming from and what format and resolution is it?
How long is your movie?
What operating system are you working on?
What happens if you select the option to burn to a folder or ISO rather than directly to a disc?
If your computer does not use an Intel HD Graphics 2000 and higher video card/graphics card, then disable the preference "Use Hardware Acceleration (works on Intel HD Graphics 2000 and higher)" and then do the burn to disc.
You could consider also incorporating deletion of the Encoded Files Folder. (See Edit Menu/Preferences/Scratch Disk and Disc Encoding to get the location for the Encoded Files Folder.)
Then do the burn to disc. Does it now work?
Just in case mention...if your computer does not use the Intel HD Graphics 2000 and higher video card/graphic card and you leave the preference mentioned enabled, you are mostly likely to run into problems with the suggestion to burn to ISO rather than directly to disc. In that type of situation, the burn to iso may or may not go to completion but the iso file cannot be found at the save location that you designated before the burn to.
We will be watching for your progress as your time permits.
For viewers of this colinb thread....
Just a note to mention that colinb in another thread
today has reported that the disabling of the Intel HD Graphics 2000 and higher preference did resolve the burn issue.
Great job, colinb.
