I know when you use all Rotel gear, it automatically senses which products you are using and lays out all the pages. If you use equipment other than Rotel, you have to learn the codes (or use preset codes), but the panel still lays out the predesigned templates for that type of product (i.e.-DVD, VCR, whatever).
One interesting thing, you can actually use the panel to browse the internet. It is recommended, however, that it not be used to do this because there is no virus protection. It is a cool product that I'm hoping to get into our shop soon to play with. It would be kinda hard to make that sell without someone getting to see the panel and play with it.
The one thing I don't like about the product is you need all the little external modules to go with it, since it's IP based.
