I've found solutions about double keypressing, but my problem is a bit different and those solutions didn't solve my trouble.
So, I have an Asus MyCinema P7131 Analog tuner, and it comes with PC-39 named remote controller.

This guy repeats my pressed button, but not "double" it instantly. For example:
I press '1':
1
Press '2':
12
Press '1:
21
Press '4':
14

My remote uses ir_rc5_decoder, or at least if I remove this module, it doesn't work at all.
I hope you have any idea should can I do.
Thanks!
