I don't have the DVD spec, but every DVD player i have seen has 
play/ffwd/frew/pause keys and a seperate set of menue control 
(up/down/left/right/ok) keys. I belive it is not possible to combine 
those to two keysets onto one common set. For excample, there are not 
enough information to decide wether the LEFT-key means a menue function 
or a fast rewind.
There are indicators that can be used to decide wether we are in a menue 
or not, but i don't belive that they are universal enough. Take the 
white rabit in 'The Matrix' as an example, that is a button function 
within a normal film sequence. The DVD OK button activates it, while the 
normal OK key activates the progess bar. If there where a second button 
present, up/down would also be needed, causing a conflict with the stop key.

I do understand that, but i believe that the ffwd, frew, play, pause and 
progessbar keys needs to be seperated from left, right, up, down and ok.

Would you mind, if i build such a configuration facility?

For recording only, i totaly agree. But as i said, full DVD capabilities 
need a bit more.

Apparently, did you get the copy i forwarded to you?
