Creating Dvd menu's

what program can I use to create DVD menu’s? I tried NVE but it makes the VOB files a bigger size when I import them.

how come Nero vision express increases the size of the files I import?

It sounds as if you are fairly new to the digital video scene. Before you jump in with both feet, I highly suggest doing some reading at Start with the guides and tutorials, then start browsing the forums. With a few simple forum searches, you will find answers to almost any question you could have about digital video, vob files, file sizes, etc…
