Doesn't make any difference.

Note that I never promised to support Rev 1.3 boards because I can't 
test it. Well, the driver seems to support it in some way and so it 
should work...

What options did you use to compile vdr, REMOTE=???
How do you start vdr/plugins. Please post the full command line.

Ok.

I do not understand why/how remote control events could be passed to a 
tty. Please explain "some keys are available on the ttys".
Which tty device(s) get(s) the remote control events?
Please post output of "ls -l /dev/input" and "ls -l /dev/ttyX"
where ttyX is the tty which gets the keys.

Just an idea: Are you using an USB keyboard?

See above. Try to compile vdr with REMOTE=NONE. 
This will disable keyboard input.

The plugin does not look for any keys, vdr does. vdr "wants" to learn 
the keys, because they are considered unknown if the "up" key is not 
defined. There is *nothing* wrong with that.
Until now, I see no reason to change anything.
We should fix the bug, not work around it.
