Hello all! 
I'm perplexed! 
I exported a 30 second clip from Adobe Premiere CS5.5 (via AME) using the Mpeg-2 DVD setting/preset. I imported the video file as a timeline into Adobe Encore, and imported the .wav file as an asset. No menus, as this was a "first play" test.
When it was time to build the project, the "bytes used" read 19.5MB. However, once the build finished, the "data written" read 550MB. This concerns me.
Q1 - Why is there such vast difference in size between the bytes used and the data written?
Q2 - My official project is nearly 2 hours. When I load it up, I'm sure "bytes used" will be multiple GB's, which is fine because I'm using a double layered DVD. However, my concern is that the data written will be gigantic! Am I assuming correctly?
IF I'm right, there is a problem. As we know, the DVD won't burn beyond the space allowed. How is it possible that Encore says there is enough space with bytes used, but the data written FAR exceeds the capacity of the DVD?
The reason I did the 30 second clip is because my first 3 attempts to burn the DVD have failed. Adobe Encore freezes and won't finish, EVENTHOUGH there was enough space on the DVD according to "bytes used". I ASSUME it's because the data WRITTEN exceeds the available space.
Is this making sense? Has anyone encountered this or have any suggestions? Do I need to provie anymore information to help assess the situation?
