Adobe Encore Question

[Kov-Ice]

In Encore when it's time to compile a disc, there are 4 options. One is to create the video files on your hard drive. I'm assuming those are the VIDEO_TS files? The docs don't name them, and they also say that you aren't to just burn those files to disc for a DVD. If they are the VIDEO_TS files, tho, couldn't you just use Nero to create a DVD disc from there?

Also, another option is to just build the project directly to disc. I did this with a one-hour video, so the program had to go through the long process of compiling the video before burning. If I hit the 'Back' button now that this is done and go to burn another copy, will Encore have to go through the whole compiling process or will it simply burn the next disc straight away?
Thanks!
