I'm using Imgburn on a new 64bit Windows 7 desktop, and I'm burning blu-ray disks which are backups of my originals. I've got it set to burn @ 1X and it's set for UDF and I'm getting alot of jerkiness in the backup when I play it. The originals fine but the backup shakes on the screen-while I can watch the movie it has the same shaking effect as say the movie cloverfield. Does anyone have any ideas?
