We need some significant differences from previous versions to make people want to get version 7. Some fetaure requests that users want may do the trick. Particularly some things that the opposition may not do.
My inital request I would like is to see Nero Express (Make DVD Video) have facilty to allow multiple audio tracks (Dobly Digital (AC-3) 5.1 or 2 channel etc) and also be able to keep a subtitle. This allows you for instance to put together a best of your video with only the bits you want to watch without having to reach for the remote to fast foward or skip. Very useful for music videos, concerts and many others uses others could think of that would suit them.
