authoring makes files bigger

[Shaorin]

I got my mpeg2 files ready to be authored it is at 4420mb and when I authored the outcome became 4516mb. I used a simple menu and I didn't uue any motions/animations. The program i used to author is TMPGEnc DVD Author 1.6. What's causing the files to grow bigger?

Authoring will make it bigger. I usually allow 100-200MB for authoring, but that's probably more than needed. A DVD-5 holds about 4.37GB, so if your program is reading the file size correctly, you're oversize anyway. TMPGEnc could also be changing the audio, though it shouldn't do anything to it if it was compliant. You may be able to check the file with Gspot before and after authoring as see where the changes were.

But you may just have to reduce the size of the MPEG before authoring.

Yeah, he's not allowing for the muxing overhead. A DVD-R holds about 4487 MB and a DVD+R holds about 4483 MB.
