No this remotes is different. RCMAP_BEHOLD has more buttons and some other scancodes.
People from linux community who was made this keymap and function for reading data from
IR decoder has error with scancode.
Our true address of scancode is
0x86 0x6B
They wrote
0x6B 0x86
Need fix some code of the saa7134-input and RCMAP_BEHOLD keytable.

RCMAP_BEHOLD_WANDER same as RCMAP_BEHOLD_COLUMBUS but
from IR decoder the saa7134 received only one byte of scancode.
Need rework saa7134-input too for get address and restore full scancodes for extended NEC full
scancodes.

I'll make it after some time.

Ok

I haven't USB stick with tm5600/6000 for test. Need people with this TV cards.

I didn't touch this code because I haven't RC5 remotes and tm5600/6000

I think your mean is wrong. Our IR remotes send extended NEC it is 4 bytes.
We removed inverted 4 byte and now we have 3 bytes from remotes. I think we
must have full RCMAP with this 3 bytes from remotes. And use this remotes with some
different IR recievers like some TV cards and LIRC-hardware and other.
No need different RCMAP for the same remotes to different IR recievers like now.

If we use second variant I can't use RCMAP_BEHOLD because it has full 3 bytes scancodes.
As you wrote.

Ok, I'll try.

I try add radio.
