[vdr] Remote control keys

[Petric Frank <pfrank@gmx.de>]

Hello,

i have a remote control (part of PVR 250) which does not have the up/down and 
left/right keys. Instead at their place i find Channel up/down and Volume 
up/down.

In using the OSD i do not need Volume / Channel keys when OSD is active. So my 
question:
How to configure vdr (probably remote.conf) to use Channel up/down and Volume 
up/down as navigation keys (up/down and left/right) ?

Any idea ?

regards
   Petric
