pioneer car remotes

[sergio <se...@ou...>]

Hello!

I'm trying to capture a new pioneer remote, but irrecord doesn't 
distinguish some buttons. As I see on xmode2 there are two types of 
buttons: the second ones are twice longer with same first half. And no 
one of the have a fixed prefix. Something like UTF-8.

xmode2 screenshot:

first tree buttons (named A, B, C on the screenshot) gives one line
last tree buttons (named D, E, F on the screenshot) gives two lines

Buttons of the first type are recorded and work fine.
Buttons of the second type are recorded the same button.
Trying to record only second type buttons fails with:

```
Now start pressing buttons on your remote control.

It is very important that you press many different buttons randomly
and hold them down for approximately one second. Each button should
generate at least one dot but never more than ten dots of output.
Don't stop pressing buttons until two lines of dots (2x80) have
been generated.

Press RETURN now to start recording.

Got gap (6463 us)}

Please keep on pressing buttons like described above.
...............................................................................
Checking for toggle bit mask.
Please press an arbitrary button repeatedly as fast as possible.
Make sure you keep pressing the SAME button and that you DON'T HOLD
the button down!.
If you can't see any dots appear, wait a bit between button presses.

Press RETURN to continue.
Cannot find any toggle mask.
But I know for sure that RC6 has a toggle bit!
zsh: exit 1     irrecord

other countries) and CD-R510 (possible CXC2665 in other countries)
