Nero Rom & Nero Express – Difference?

Well,

I know Nero express is simplified version of Nero Rom, but what exactly is the difference?
Using either will make any difference ?
Please clear

PS: Talking about latest Nero 7 version

Any1 ?

With Nero 7 Essentials (which includes Nero Express), certain elements, like Nero Showtime, are trial versions; you’ll be prompted to pay for the full version if you want certain features.

Nero Express is basically a dumbed-down version of Nero Burning ROM. Not as many advanced features as the full Nero Burning ROM.

That’s just what I’ve noticed with the Nero 7 Essentials that came with my other PC.

Well… i have full version nero 7…
and wana burn my DVD-R … but wonder which option woud be better… via ROM OR EXPRESS…
