They are at drivers/media/common/ir-keymaps.c in the current v4l-dvb
I try with ir_codes_avermedia and works well.
ir_codes_avermedia_dvbt is for avermedia 771 remote.
In kernels <= 2.6.16 you can use md2819_codes that are in saa7134-input.c and 
work well too.
The problem when press the same key is because:
In line 58 of saa7134-input.c:

gpio = saa_readl(SAA7134_GPIO_GPSTATUS0 >> 2);

always return the last key pressed.
And I don't know how to clear the last key pressed from gpio.
