right for VDR, but DVD spec requires them ...

mhh, the "Eject" function could actualy be more than "throw out that disc", it 
could also mean "umount and spin down that HD", "detach/deactivate that USB 
storage device", "prepare that IDE/SCSI device for hot swap", and so on. 
Those are functions that will have to provided though external 
script/programs, but it makes sense to be able to trigger them through vdr's 
remote. That was also the reason for the eject menu mentioned above.

disputable, _every_ VCR in existence has a Record button.

mhh, i do have my problems with using the color keys, however there are valid 
reasons to usem them on certain remotes and reasons not to do so on others 
(my remote has no colors, but plenty of ffwd, freeze, ... keys).

It would appear that my function key list does not interfer with yours, maybe 
there is a sensible way to combine them.
There could be two minimal remote definitions, the current color key based and 
an alternate function key based maping. Both having a minimal set of keys 
with optinal additions. The _ultimate_ remote could then just have them all.

I was missing one or two keys from my initial list, i'll draw up a table (like 
the one in vdr's manual) that compares both mappings.
